AB  - The Cambridge Structural Database (CSD) is searched for mutual contacts between six-membered resonance-assisted hydrogenbridged
rings (RAHB) (the example of a fragment is shown in Fig. 1a) [1] and for contacts between six-membered RAHB rings and
C6-aromatic rings (Fig. 1b). There is a quite large prevalence of parallel contacts in the set of RAHB/RAHB contacts, since 91% from
totally 678 contacts found are parallel contacts, mostly with antiparallel orientation of the rings [1]. At the other side, the prevalence of
parallel contacts in the set of RAHB/C6-aromatic contacts is not so pronounced, since 59% from totally 677 contacts found are parallel
contacts. The distances between the interacting ring planes are mostly between 3.0 and 4.0 Å, while horizontal displacements are
mostly in the range 0.0-3.0 Å in both parallel RAHB/RAHB and RAHB/C6-aromatic contacts.
The interaction energy calculations were performed on stacked dimer model systems based on abundance in the CSD. The strongest
calculated RAHB/RAHB interaction is -4.7 kcal/mol, while the strongest calculated RAHB/benzene interaction is significantly weaker
-3.7 kcal/mol. However, RAHB/RAHB stacking interactions can be stronger or weaker than the corresponding RAHB/benzene
stacking interactions, depending on the RAHB ring system. The Symmetry Adopted Perturbation Theory (SAPT) calculations show
that the dominant contribution in total RAHB/RAHB stacking interaction energy is the dispersion term, which can be mostly or
completely cancelled by the exchange repulsion term, hence, the electrostatic term can be effectively dominant. Depending on the
RAHB ring system, the electrostatic contribution can be practically equal to the net dispersion contribution (the sum of dispersion and
exchange-repulsion terms) [1]. The electrostatic term is effectively dominant in all RAHB/benzene systems observed, due to the
almost complete cancellation of the dispersion by the exchange-repulsion terms.

AB  - In the recent review it was point out that the crystal structures in the Cambridge Structural Database (CSD), collected, have contribute
to various fields of chemical research such as geometries of molecules, noncovalent interactions of molecules, and large assemblies of
molecules. The CSD also contributed to the study and the design of biologically active molecules and the study of gas storage and
delivery [1].
In our group we use analysis of the crystal structures in the CSD to recognize and characterize new types of noncovalent interactions
and to study already known noncovalent interactions. Based on the data from the CSD we can determine existence of the interactions,
frequency of the interactions, and preferred geometries of the interactions in the crystal structures. In addition, we perform quantum
chemical calculations to evaluate the energies of the interactions. Based on the calculated potential energy surfaces for the
interactions, we can determine the most stable geometries, as well as stability of various geometries. We also can determine the
interaction energies for the preferred geometries in the crystal structures. In the cases where the most preferred geometries in the
crystal structures are not the most stable geometries at the potential energy surface, one can find significant influence of the
supramolecular structures in the crystals.
Using this methodology our group recognized stacking interactions of planar metal-chelate rings; stacking interactions with organic
aromatic rings and stacking interactions between two chelate rings. The calculated energies indicate strong stacking interactions of
metal-chelate rings; the stacking of metal-chelate rings is stronger than stacking between two benzene molecules [2]. The data indicate
influence of the metal and ligand type in the metal chelate ring on the strength of the interactions. Our results also indicate strong
stacking interactions of coordinated aromatic rings [3]. Studies of interactions of coordinated water indicate stronger hydrogen bonds
and stronger OH/π interactions of coordinated in comparison to noncoordianted water molecule [4,5]. The calculations on OH/M
interactions between metal ion in square-planar complexes and water molecule indicate that these interactions are among the strongest
hydrogen bonds in any molecular system [6].
The studies on stacking interactions of benzene molecules in the crystal structures in the CSD show preference for interactions at large
horizontal displacements, while high level quantum chemical calculations indicate significantly strong interactions at large offsets; the
energy is 70% of the strongest stacking geometry [7].

AB  - Stacking interactions between six-membered resonance-assisted hydrogen-bridged rings (RAHB) and C6-aromatic rings are systematically studied by analyzing crystal structures in Cambridge Structural Database (CSD). The interaction energies were calculated by quantum-chemical methods. Although the interactions are stronger than benzene/benzene stacking interactions (-2.7 kcal/mol) the strongest calculated RAHB/benzene stacking interaction (-3.7 kcal/mol) is significantly weaker than the strongest calculated RAHB/RAHB stacking interaction (-4.7 kcal/mol), but for particular composition of RAHB rings RAHB/benzene stacking interactions can be weaker or stronger than the corresponding RAHB/RAHB stacking interactions. They are also weaker than the strongest calculated stacking interaction between five-membered saturated hydrogen-bridged rings and benzene (-4.4 kcal/mol) and between two five-membered saturated hydrogen-bridged rings (-4.9 kcal/mol). SAPT energy decomposition analyses show that the strongest attractive term in RAHB/benzene stacking interactions is dispersion, however, it is mostly canceled by repulsive exchange term, hence the geometries of the most stable structures are determined by electrostatic term.

AB  - The study of crystal structures from the Cambridge Structural Database (CSD) shows that most of p-phenol/p-phenol and toluene/toluene stacking interactions are at large horizontal displacements (offsets) as well as benzene/benzene interactions. The interactions at large horizontal displacements are stabilized by the addition of simultaneous interactions in supramolecular structures in crystals. The stacking p-phenol/p-phenol tends to be orientated in a parallel and antiparallel fashion, while stacking toluene/toluene is almost all in an antiparallel orientation. It is in accordance with calculated interaction energies. Namely, the strongest interaction energies for parallel and antiparallel phenol/phenol dimers are −5.12 and −4.40 kcal/mol, at offsets of 1.5 and 3.0 Å, respectively, while for parallel and antiparallel toluene/toluene dimers, energies are −3.98 and −5.39 kcal/mol, at offsets of 3.0 Å. These interactions are stronger than benzene/benzene stacking (−2.85 kcal/mol), as a consequence of the presence of the substituents. Similar to benzene/benzene stacking, interactions for phenol/phenol and toluene/toluene stacking at large offsets (4.0 Å) can be strong, stronger than −2.0 kcal/mol.

AB  - Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations. Statistical analysis of the geometrical data from the Cambridge Structural Database (CSD) reveals that in most cases, interactions between sulfur and disulfide bonds are bifurcated. Quantum chemical calculations are in agreement with those findings. A strong interaction energy was calculated for bifurcated interactions (ECCSD(T)/CBS = −2.83 kcal mol−1) considering the region along the disulfide bond. Non-bifurcated interactions are weaker except in cases where σ-hole interaction is possible or in cases where S⋯S interaction is accompanied by additional hydrogen bonds (ECCSD(T)/CBS = −3.26 kcal mol−1). SAPT decomposition analysis shows that dispersion is the main attractive force in the studied systems while electrostatics plays a crucial role in defining the geometry of interactions.Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations.

AB  - Supramolecular arrangements of RAHB/RAHB and RAHB/C6-aromatic contacts were studied by the Cambridge Structural Database (CSD) search, while interaction energies of these interactions were calculated on dimer model systems by using quantum-chemical methods. Parallel alignment contacts are quite dominant in the crystal structures of these species, since 91% of the RAHB/RAHB contacts, satisfying the search criteria [1], are parallel, while that preference is not so large in RAHB/C6-aromatic contacts, since 59% of them are parallel [2]. Interplane separations of the parallel contacts of both systems are between 3.0 and 4.0 Å, which is a characteristic of stacking interactions. Examples of the RAHB/RAHB and RAHB/C6-aromatic contacts are given in Figure 1.
Model systems for quantum chemical calculations are based on abundance in the crystal structures. Energy decomposition analysis is also performed by using Symmetry Adopted Perturbation Theory (SAPT) calculations. The strongest calculated RAHB/RAHB interaction is -4.7 kcal/mol. Electrostatic contribution is dominant or equal to the net dispersion (the sum of dispersion and exchange-repulsion terms). The strongest calculated RAHB/benzene interaction is -3.7 kcal/mol, but RAHB/benzene interactions can be stronger or weaker than the corresponding RAHB/RAHB interactions.

AB  - Amyloids are proteins of a cross-β structure found as deposits in several diseases and also in normal tissues (nails, spider net, silk). Aromatic amino acids are frequently found in amyloid deposits. Although they are not indispensable, aromatic amino acids, phenylalanine, tyrosine and tryptophan, enhance significantly the kinetics of formation and thermodynamic stability, while tape or ribbon-like morphology is represented in systems with experimentally detected π-π interactions between aromatic rings. Analysis of geometries and energies of the amyloid PDB structures indicate the prevalence of aromatic-nonaromatic interactions and confirm that aromatic-aromatic interactions are not crucial for the amyloid formation.

AB  - To figure out the possible role of 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) as well as to provide reference thermochemical data in solution, the formation of Lewis acid-base complexes between HFIP (Lewis acid) and a series of 8 different Lewis bases (3 sulfoxides, 3 Nsp2 pyridine derivatives, 1 aromatic amine, 1 cyclic aliphatic ether) was examined by isothermal titration calorimetry (ITC) experiments and static density functional theory augmented with Dispersion (DFT−D) calculations. Measured ITC association enthalpy values (ΔHa) lie between −9.3 and −14 kcal mol−1. Computations including a PCM implicit solvation model produced similar exothermicity of association of all studied systems compared to the ITC data with ΔHa values ranging from −8.5 to −12.7 kcal mol−1. An additional set of calculations combining implicit and explicit solvation by chlorobenzene of the reactants, pointed out the relatively low interference of the solvent with the HFIP-base complexation: its main effect is to slightly enhance the Gibbs energy of the HFIP-Lewis base association. It is speculated that the interactions of bulk HFIP with Lewis bases therefore may significantly intervene in catalytic processes not only via the dynamic microstructuring of the medium but also more explicitly by affecting bonds’ polarization at the Lewis bases.

AB  - The thermochemistry of the aminolysis of three methoxy Fischer carbenes, pentacarbonyl(phenylmethoxyalkylidene)chromium(0), molybdenum(0) and tungsten(0), was studied experimentally and theoretically with three amines, namely benzylamine, aniline and 3-pyrroline. Enthalpies of reactions were all determined by Isotherm Calorimetric Titration (ITC) in chlorobenzene at 298.15 K, which provided in almost all cases values of ΔrH larger than -15 kcal/mol suggesting energetically favourable transformations for all amines except aniline. No significant dependence of the enthalpy of reaction upon the nature of the metal atom of the carbene complex was found. Further ITC experiments confirmed the partial second-order reaction in amine. All COSMO-DFT computed enthalpies of reaction (spanning ca. -5.5 kcal/mol up to -20 kcal/mol) were found to be in excellent agreement with experimental values, while calculated Gibbs free energies suggested spontaneous processes for all reactions except the one with aniline.

AB  - Two-dimensional (2D) halogen-bonded organic frameworks were readily engineered by strong and directional effects of the primary Br⋯O and the secondary Br⋯π halogen bonding interactions from the tetrabromobenzene-1,4-dicarboxylic acid (H2Br4BDC) building molecule involving 100% supramolecular yields. The 2D assembly can function as a host layered framework for the intercalation of various guest solvents including acetone (ATN), ethanol (EtOH), dimethyl sulfoxide (DMSO), and ethylene glycol (EG) resulting in a 1 : 2 host : guest complexation stoichiometry viz. H2Br4BDC·2S (S = ATN (1ATN), EtOH (2EtOH), DMSO (3DMSO), and EG (4EG)). All the solvates show remarkable similarities in their 2D layered sheets and the bilayer distance significantly responds to the size, shape, molecular conformation, and strength of the hydrogen bonding capability of the intercalated solvent molecules. The transition between solvate formation and desolvation was found to be facile and reversible upon the desolvation-resolvation process. The estimated Br⋯O halogen bonding energy of the solvates is in the -0.6 to -1.7 kcal mol-1 range, which was determined by quantum-mechanical calculations based on density functional theory (DFT) calculations. Furthermore, to quantitatively identify the host-guest intermolecular interactions of these solvates, they were visually compared by Hirshfeld surface analysis.

AB  - High-level ab initio calculations show that the most stable stacking for benzene-cyclohexane is 17% stronger than that for benzene-benzene. However, as these systems are displaced horizontally the benzene-benzene attraction retains its strength. At a displacement of 5.0 Å, the benzene-benzene attraction is still ∼70% of its maximum strength, while benzene-cyclohexane attraction has fallen to ∼40% of its maximum strength. Alternatively, the radius of attraction (>2.0 kcal/mol) for benzene-benzene is 250% larger than that for benzene-cyclohexane. Thus, at relatively large distances aromatic rings can recognize each other, a phenomenon that helps explain their importance in protein folding and supramolecular structures.

AB  - In the crystal structures of methylated cyclopentadienyl (Cp) complexes (MeCp, Me4Cp and Me5Cp) deposited in the Cambridge Structural Database, certain orientation types of stacked contacts can be noted as the most frequent. These orientation preferences can be well explained by the matching of oppositely charged regions of electrostatic potential. Parallel displaced stacking, large offset stacking and C - H⋯π interactions are the dominant interaction types that are responsible for the arrangement in the crystal structures of stacked methylated Cp complexes.

AB  - The interaction of water molecules with aromatic rings is of great importance in many systems, from biological molecules to materials. The results of the research on OH/π interactions of liquid water and benzene show that they have an important role in biological binding and recognition. The strength of the interactions between ammonia and aromatic systems have shown that NH/π interactions can be taken into consideration during the modeling of the structures of biological systems.This doctoral dissertation is in the field of non-covalent interactions between water and ammonia molecules with aromatic systems, as well as the influence of water and ammonia coordination on those interactions. To study the interactions between water (noncoordinated and coordinated) and aromatic rings, OH/π and parallel interactions have been examined. Data obtained from the Cambridge Structural Database (CSD) and data obtained on the basis of the quantum-chemical calculations have been analyzed. The data obtained from the CSD show that parallel interactions are more numerous than OH/π interactions. Coordination of water to a metal ion affects the strength of interactions with aromatic ring, the interactions of the aqua complexes are stronger. Calculations at MP2/def2-QZVP level of the OH/π interactions in water/benzene system yield the energy of -3.36 kcal/mol, while for the [Zn(H2O)6]2+/C6H6 system it is -13.96 kcal/mol. Coordinated water molecules prefer parallel-down orientation relative to the aromatic ring. The energy of this interaction for H2O/C6H6 system is -3.11 kcal/mol, while the strongest calculated interaction is -14.89 kcal/mol and it refers to the [Zn(H2O)6]2+/C6H6 system.Coordination of ammonia to a metal ion affects its MLNH/π interactions with benzene. Coordinated ammonia tends to approach the aryl group closer than noncoordinated ammonia. The energy of NH/π interaction for the NH3/C6H6 system is -2.30 kcal/mol, while for the system [Zn(NH3)6]2+/C6H6 it is -14.77 kcal/mol. Quantum-chemical calculations show agreement with the conclusions derived from the crystal structures analysis from the CSD.

AB  - Early experimental and theoretical evidences of the existence of platinum-hydrogen 
interactions emerged more than four decades ago [1]. Although metal atoms are not 
usually seen as hydrogen atom acceptors, many crystallographic studies as well as our 
recent quantum chemical study, showed that they can be involved in very strong 
hydrogen bonding [2].
In this work, energies and geometries of X-H/Pt interactions involving cisplatin and 
transplatin molecules as hydrogen atom acceptors and different hydrogen atom donors 
were evaluated. Interaction energies and optimal geometries were calculated using 
MP2/aug-cc-PVDZ level of theory. Cambridge Structural Database search was 
performed and all structures containing cisplatin and transplatin molecules involved in 
X-H/Pt interactions were extracted. Geometrical parameters important for the analysis 
of X-H/Pt interactions were statistically analysed.
Results indicated that there are significant differences in metal-hydrogen bonding 
between cisplatin and transplatin molecules. The energy of the strongest X-H/Pt 
interactions involving cisplatin molecule are calculated to be EO-H/cis-Pt = –5.97 kcal/mol 
while interaction energy of the strongest X-H/Pt interactions involving transplatin 
molecule was calculated to be EO-H/trans-Pt = –4.43 kcal/mol. Electrostatic potential maps were 
calculated for both cisplatin and transplatin molecules and used to explain trends in 
interaction energies. Results of interaction energies calculations were in excellent 
agreement with the results of statistical analysis of crystallographic data.

AB  - Наше истраживање се заснива на анализи података у кристалним структурама
из Кембичке базе структурних података (CSD) и на квантнo хемијским
прорачунима. Анализа података из CSD-а омогућава да се препознају интеракције у
кристалним структурама и да се опишу геометрије ових интеракција, док помоћу
квантно-хемијских прорачуна можемо проценити интеракционе енергије и пронаћи
најстабилније геометрије интеракција. Користећи ову методологију успели смо да
препознамо и опишемо неколико нових типова интеракција.
Наше проучавање интеракција планарних метал-хелатних прстенова показало је
могућност стекинг интеракција са органским ароматичним прстеновима и
интеракције између два хелатна прстена. Израчунате енергије указују на јаке
стекинг интеракције метал-хелатних прстенова; стекинг метал-хелатних прстенова
је јачи од стекинга између два молекула бензена. Испитивања интеракција
координираних молекула воде и амонијака указују на јаче водоничне везе и јаче
ОH/π и NH/π интеракције координираних у односу на некоординоване молекуле
воде и амонијака. Прорачуни ОH/М интеракција између металног јона у квадратнo
планарним комплексима и молекулa воде указују да су ове интеракције међу
најјачим водоничним везама у било ком молекулском систему.
Студије о ароматичним молекулима указују на стекинг интеракције са великим
хоризонталним померањима између два ароматична молекула са значајно јаким
интеракцијама, енергија је 70% најјаче стекинг интеракције. Наши подаци такође
указују на то да су интеракције алифатичних прстенова са ароматичним прстеном
јаче од интеракција између два ароматична молекула, док су
алифатично/ароматичне интеракције веома честе у протеинским структурама.
AB  - Our research is based on analyzing data in crystal structures from the Cambridge
Structural Database (CSD) and on quantum chemical calculations. The analysis of the
data from the CSD enable to recognize interactions in crystal structures and to describe
the geometries of these interactions, while by quantum chemical calculations we can
evaluate interaction energies and find the most stable interaction geometries. Using this
methodology we were able to recognize and describe several new types of noncovalent
interactions.
Our study of planar metal-chelate rings interactions showed possibility of chelate ring
stacking interactions with organic aromatic rings, and stacking interactions between two
chelate rings. The calculated energies indicate strong stacking interactions of metalchelate rings; the stacking of metal-chelate rings is stronger than stacking between two
benzene molecules. Studies of interactions of coordinated water and ammonia indicate
stronger hydrogen bonds and stronger OH/π and NH/π interactions of coordinated in
comparison to noncoordianted water and ammonia. The calculations on OH/M interactions between metal ion in square-planar complexes and water molecule indicate that
these interactions are among the strongest hydrogen bonds in any molecular system.
The studies on aromatic molecules indicate stacking interactions at large horizontal
dispacements between two aromatic molecules with significantly strong interacitons, the
energy is 70% of the strongest stacking geometry. Our data also indicate that stacking
interactions of an aliphatic rings with an aromatic ring are stonger than interactions between two aromatic molecules, while aliphatic/aromatic interactions are very frequent in
protein structures.

abstract = "Наше истраживање се заснива на анализи података у кристалним структурама
из Кембичке базе структурних података (CSD) и на квантнo хемијским
прорачунима. Анализа података из CSD-а омогућава да се препознају интеракције у
кристалним структурама и да се опишу геометрије ових интеракција, док помоћу
квантно-хемијских прорачуна можемо проценити интеракционе енергије и пронаћи
најстабилније геометрије интеракција. Користећи ову методологију успели смо да
препознамо и опишемо неколико нових типова интеракција.
Наше проучавање интеракција планарних метал-хелатних прстенова показало је
могућност стекинг интеракција са органским ароматичним прстеновима и
интеракције између два хелатна прстена. Израчунате енергије указују на јаке
стекинг интеракције метал-хелатних прстенова; стекинг метал-хелатних прстенова
је јачи од стекинга између два молекула бензена. Испитивања интеракција
координираних молекула воде и амонијака указују на јаче водоничне везе и јаче
ОH/π и NH/π интеракције координираних у односу на некоординоване молекуле
воде и амонијака. Прорачуни ОH/М интеракција између металног јона у квадратнo
планарним комплексима и молекулa воде указују да су ове интеракције међу
најјачим водоничним везама у било ком молекулском систему.
Студије о ароматичним молекулима указују на стекинг интеракције са великим
хоризонталним померањима између два ароматична молекула са значајно јаким
интеракцијама, енергија је 70% најјаче стекинг интеракције. Наши подаци такође
указују на то да су интеракције алифатичних прстенова са ароматичним прстеном
јаче од интеракција између два ароматична молекула, док су
алифатично/ароматичне интеракције веома честе у протеинским структурама., Our research is based on analyzing data in crystal structures from the Cambridge
Structural Database (CSD) and on quantum chemical calculations. The analysis of the
data from the CSD enable to recognize interactions in crystal structures and to describe
the geometries of these interactions, while by quantum chemical calculations we can
evaluate interaction energies and find the most stable interaction geometries. Using this
methodology we were able to recognize and describe several new types of noncovalent
interactions.
Our study of planar metal-chelate rings interactions showed possibility of chelate ring
stacking interactions with organic aromatic rings, and stacking interactions between two
chelate rings. The calculated energies indicate strong stacking interactions of metalchelate rings; the stacking of metal-chelate rings is stronger than stacking between two
benzene molecules. Studies of interactions of coordinated water and ammonia indicate
stronger hydrogen bonds and stronger OH/π and NH/π interactions of coordinated in

AB  - Chelate-aryl and chelate-chelate stacking interactions of nickel bis(dithiolene) were studied at the CCSD(T)/CBS and DFT levels. The strongest chelate-aryl stacking interaction between nickel bis(dithiolene) and benzene has a CCSD(T)/CBS stacking energy of -5.60 kcal mol-1. The strongest chelate-chelate stacking interactions between two nickel bis(dithiolenes) has a CCSD(T)/CBS stacking energy of -10.34 kcal mol-1. The most stable chelate-aryl stacking has the benzene center above the nickel atom, while the most stable chelate-chelate dithiolene stacking has the chelate center above the nickel atom. Comparison of chelate-aryl stacking interactions of dithiolene and acac-type nickel chelate shows similar strength. However, chelate-chelate stacking is stronger for dithiolene nickel chelate than for acac-type nickel chelate, which has a CCSD(T)/CBS interaction energy of -9.50 kcal mol-1. © 2018 the Owner Societies.

AB  - X−H/Pt interactions between cisplatin (cis-[Pt(NH3)2Cl2]) and transplatin (trans-[Pt(NH3)2Cl2]) molecules as hydrogen atom acceptors and CH4, NH3 and H2O molecules as hydrogen atom donors were studied by quantum chemical calculations and analysis of crystallographic data from Cambridge Structural Database (CSD). Results of interaction energies calculations showed that almost in all cases cisplatin molecule forms stronger X−H/Pt interaction compared to transplatin molecule. The strongest calculated interaction is O−H/Pt interaction between cisplatin and a water molecule with the energy ΔEMP2/aug-cc-PVDZ=-5.97 kcal/mol; calculated energy of the strongest transplatin/water interaction is ΔEMP2/aug-cc-PVDZ=-4.43 kcal/mol. Only in case of C−H/Pt interactions translplatin molecule forms slightly stronger interaction compared to cisplatin molecule; the energy of the strongest C−H/Pt interaction involving transplatin molecule is ΔEMP2/aug-cc-PVDZ=-1.20 kcal/mol while for cisplatin energy is ΔEMP2/aug-cc-PVDZ=-1.08 kcal/mol. Interaction energies for geometries with the strongest X−H/Pt interactions were re-calculated at CCSD(T)/CBS level and these results were in excellent agreement with results obtained at MP2/aug-cc-PVDZ level of theory. Electrostatic potentials were calculated and used to explain results of interaction energies calculations. Analysis of geometrical data revealed that cisplatin and transplatin molecules are involved in X−H/Pt contacts in crystal structures.

AB  - The interactions of nucleic acid bases with non-coordinated and coordinated water molecules were studied by analyzing data in the Protein Data Bank (PDB) and by quantum chemical calculations. The analysis of the data in the crystal structures from the PDB indicates that hydrogen bonds involving oxygen or nitrogen atoms of nucleic acid bases and water molecules are shorter when water is bonded to a metal ion. These results are in agreement with the quantum chemical calculations on geometries and interaction energies of hydrogen bonds; the calculations on model systems show that hydrogen bonds of nucleic acid bases with water bonded to a metal ion are stronger than hydrogen bonds with non-coordinated water. These calculated values are similar to the strength of hydrogen bonds between nucleic acid bases. The results presented in this paper may be relevant to understand the role of water molecules and metal ions in the process of replication and stabilization of nucleic acids and also to understand the possible toxicity of metal ion interactions with nucleic acids.
