AB  - The hydrogen bonds of noncoordinated (NH/O) and coordinated ammonia (MLNH/O) with water molecules were studied by analyzing data in the Cambridge Structural Database (CSD) and by DFT calculations. The data from the CSD on the distribution of hydrogen bond dHO distances of the coordinated ammonia show a peak in the range of 2.0–2.2 Å with a significant number of hydrogen bonds in the range of 1.8–2.0 Å. Analysis of Hirshfeld surfaces showed that coordinated NH3 molecules are involved in numerous noncovalent contacts. The DFT calculations were performed on linear complexes of silver(I), square-planar complexes of platinum(II), tetrahedral complexes of zinc(II), and octahedral complexes of cobalt(III) by varying the charge of the complexes. The calculated data show that coordinated ammonia has stronger hydrogen bonds than noncoordinated ammonia, even for neutral complexes. The hydrogen bond energy of noncoordinated ammonia is −2.3 kcal/mol, while for coordinated ammonia, attractive interactions are in the range of −3.7 to −25.0 kcal/mol, depending on the metal ion and charge of the complex. The interaction energies for metal complexes from neutral to charged species are for the linear silver(I) complex from −6.0 to −10.7 kcal/mol, while for the square planar complex, interactions span from −5.9 to −19.9 kcal/mol. The tetrahedral zinc(II) complexes have interaction energy from −5.5 to −17.5 kcal/mol, while for the octahedral cobalt(III) complex, attractive interaction energies are from −3.7 to −25.0 kcal/mol. With the increasing charge of the metal complex, the hydrogen bond between coordinated ammonia and free water becomes stronger, and in accordance with that, the dHO distance becomes shorter. The bifurcated interaction is stronger than monofurcated for all complexes. The interaction energies correspond well with the electrostatic potential (Vs) values on interacting hydrogen atoms; the more positive Vs values on hydrogen atoms lead to stronger interaction. The hydrogen bond between ammonia and water molecules (−2.3 kcal/mol) is quite weak in comparison to the water/water hydrogen bond; it is 50% of the water/water hydrogen bond (−4.84 kcal/mol). Although the hydrogen bonds of coordinated ammonia are also weaker than hydrogen bonds of coordinated water molecules, the difference is smaller, indicating the importance of the coordination on the strength of hydrogen bonds.

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  - The analysis of the crystal structures in the CSD was used to recognize and characterize new types of noncovalent interactions. It was also used 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 [1,2].
The quantum chemical calculations were performed to evaluate the energies of the interactions. For the preferred geometries in the crystal structures we can calculate the interaction energies. By calculating potential energy surfaces for the interactions, we can determine the most stable geometries, as well as stability of various geometries [1,2].
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 showed that the stacking of metal-chelate rings is stronger than stacking between two benzene molecules. Studies of interactions of coordinated ligands indicate stronger noncovalent interactions that interactions of noncoordinated molecules [2].

AB  - The development of new classes of high energetic materials (HEM) with high efficiency and low impact sensitivity is in the focus of
numerous experimental and theoretical studies [1]. However, the high efficiency of HEM molecules is usually related to the high
sensitivity towards detonation [2]. It is known that the sensitivity of HEM molecules towards detonation depends on many factors,
including oxygen balance, energy content, and positive values of electrostatic potential above the central regions of the molecular
surface. Analysis of positive values of molecular electrostatic potentials (MEP) showed to be an excellent tool in the assessment of
impact sensitivities of high energetic molecules since positive values of MEP above the central regions of molecules are associated
with high sensitivity towards detonation of HEM molecules [2]. Here we analysed the influence of hydrogen bonding on the values of
the electrostatic potentials of fragments of HEM molecules extracted from crystal structures [3].
Crystal structures of three selected high energetic molecules were extracted from Cambridge Structural Database (CSD) and analysed
in terms of non-covalent interactions. Three well-known HEM molecules were selected for the analysis: 1,3,5-Trinitrobenzene (TNB),
2,4,6-Trinitrophenol (TNP), and 2,4,6-Trinitrotoluene (TNT). Geometries of these molecules were used for electrostatic potentials
calculations and for the design of model systems for interaction energies calculations. Electrostatic potential maps were calculated for
TNB, TNP, and TNT geometries extracted from crystal structures for free molecules and molecules involved in hydrogen bonding.
Values of electrostatic potentials above the central regions of molecules were analysed and compared for non-bonded HEM molecules
and HEM molecules involved in hydrogen bonding.
Analysis of crystal structures showed that selected HEM molecules are involved in three types of hydrogen bonds: O-H…O-N
interactions, C-H…O-H interactions, and in the case of TNP molecule O-H…O-H interactions. Analysis of positive values of the
electrostatic potentials showed that hydrogen bonds have a significant influence on the values of the electrostatic potential in the
central regions of HEM molecules. Calculations performed at M06/cc-PVDZ level showed that in the case when HEM molecules are
involved in hydrogen bonding as hydrogen atom donors, positive values of electrostatic potentials in the centres of molecules
decreased by 20 – 25%. In the case when HEM molecules were involved in hydrogen bonding as hydrogen atom acceptors, positive
values of electrostatic potentials in the centres of HEM molecules increased by 10%.
Results presented in this study show that hydrogen bonds could be used as a tool for the modification of positive values of MEP above
the central regions of HEM molecules and for the modification of their sensitivities towards detonation. Moderate change of positive
electrostatic potential values above the central regions of HEM molecules upon formation of hydrogen bonds provide an opportunity
for fine-tuning of sensitivities of HEM molecules towards detonation.

AB  - Design of new classes of high energetic materials (HEM) with lower sensitivity towards 
detonation is the ultimate goal of numerous experimental and theoretical studies.[1] One 
of the most important properties that define the impact sensitivity of HEM molecules is 
the value of molecular electrostatic potential (MEP) above the central regions of molecular 
surface. Positive values of MEP are strongly related to high sensitivity of HEM molecules 
towards detonation.[2] In our previous work, we showed that it is possible to modify MEP 
of chelate complexes by careful selection of ligands and metal atoms.[3] In this work, we 
calculated MEPs for series of metallocene molecules and analysed results in the context 
of their possible detonation properties. 
Calculations performed at B3LYP/def2TZVP level showed that negative values of MEP above 
the center of the cyclopentadienyl ligand of ferrocene (-16.55 kcal/mol) were changed to 
positive values (7.11 kcal/mol) upon the addition of NO2 substituent to cyclopentadienyl 
ligand. Results of DFT calculations also showed that changing of transition metal atom 
in metallocene molecule could be used for fine-tuning of electrostatic potential values 
above the central region of cyclopentadienyl ligands.

AB  - Geometries and energies of Pt...H interactions were studied using analysis of crystallographic data
and quantum chemical calculations. Cambridge Structural Database (CSD) was searched for all
crystal structures containing X-Pt...H-OH interactions. Analysis of geometrical parameters in crystal
structures showed that in majority of crystal structures X-Pt...H interactions do not have tendency for linear arrangement. Based on the results of analysis of geometrical parameters, model systems for quantum chemical calculations were made. Results of quantum chemical calculations showed that in case of linear X-Pt...H arrangement (angle X-Pt-H = 180°) between PtS molecule and water calculated intermolecular interactions are repulsive, while in case of X-Pt...H interaction with the X-Pt-H angle value of 90° the interaction is attractive (ΔE = -2.42 kcal/mol). These results of quantum chemical calculations are in good agreement with the results of the analysis of crystallographic data.

The data show a larger influence of crystal packing/surrounding, more than the influence of substituents, on geometries of aromatic/aromatic interactions. While the interactions in crystal structures from the CSD show preference for parallel stacking interactions at the large offsets, in proteins from the PDB, they show preference for T-shaped geometries with small offsets.

AB  - In an effort to determine the thermochemistry of established organometallic transformation, the well documented reaction of alkynes with a palladacycle was investigated by isothermal titration calorimetry (ITC). Although the mechanism of the insertion of unsaturated substrates into the Pd−C bond of cyclopalladated compounds is known, no information is available so far about their thermochemistry. The enthalpies of the reactions of Ph−C≡C−Ph and MeOC(O)−C≡C(O)COMe with the bisacetonitrilo salt of the N,N-benzylamine palladacycle were determined by ITC in chlorobenzene after having optimized the conditions to ensure that only the double and a single insertion of alkynes were occurring respectively. The reaction energy profile established by DFT for the double insertion process involving Ph−C≡C−Ph confirmed earlier conclusions on the rate determining character of the first insertion. Further computations of reaction enthalpies reveal significant discrepancies between ITC and DFT-D/continuum solvation enthalpies, that are suspected to arise from an unexpected explicit noncovalent interaction of PhCl with the components of the reaction.

New Type of Aromatic π-Systems for Anion Recognition: Strong Anion-π and C−H⋅⋅⋅Anion Interactions Between Halides and Aromatic Ligands in Half-Sandwich Compounds

AB  - Half-sandwich compounds of benzene, cyclopentadienyl, pentamethylcyclopentadienyl, and indenyl were studied as a new type of aromatic π-systems for interactions with halide anions. Although uncoordinated benzene forms only C−H⋅⋅⋅anion interactions, and hexafluorobenzene forms only anion-π interactions, aromatic ligands in half-sandwich compounds can form both types of interactions, because their entire electrostatic potential surface is positive. These aromatic ligands can form stronger anion-π interactions than organic aromatic molecules, as a consequence of more pronounced dispersion and induction energy components. Moreover, C−H⋅⋅⋅anion interactions of aromatic ligands are stronger than anion-π interactions, and significantly stronger than C−H⋅⋅⋅anion interactions of benzene. Our study shows that transition-metal coordination can make aromatic moieties suitable for strong interactions with anions, and gives insight into the design of new anion receptors.

AB  - The stacking contacts between two resonance-assisted hydrogen-bridged (RAHB) rings and stacking contacts between RAHB rings and C6-aromatic groups are frequently found at large horizontal displacements in the crystal structures found in the Cambridge Structural Database (CSD), particularly in the range of 4.0–6.0 and 5.5–6.5 Å, respectively. Ab initio calculations reveal that interactions at large offsets, although weaker than interactions at smaller offsets, can be significant, since a large portion of interaction energy (in some systems up to 66%) can be preserved upon shifting to larger offset values.

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  - The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallography structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were calculated using quantum chemical method. We found 1913 sugar/aromatic ring contacts, 1054 of them (55%) with CH/π interactions and 859 of them (45%) without CH/π interactions. We showed that only the carbohydrate/aromatic contacts with CH/π interactions are preferentially parallel and enable sliding in the plane parallel to aromatic ring. The calculated interaction energies in systems with CH/π interactions are in the range from −1.7 kcal/mol to −6.8 kcal/mol, while in the systems without CH/π interactions are in the range −0.2 to −3.2 kcal/mol. Hence, the binding that does not include CH/π interactions, can also be important for aromatic amino acid and carbohydrate binding processes, since some of these interactions can be as strong as the CH/π interactions. At the same time, these interactions can be weak enough to enable releasing of small carbohydrate fragments after the enzymatic reaction. The analysis of the protein-substrate patterns showed that every second or third carbohydrate unit in long substrates stacks with protein aromatic amino acids.
