Computational study of the spin-state energies and UV-Vis spectra of bis(1,4,7-triazacyclononane) complexes of some first-row transition metal cations
(Royal Soc Chemistry, Cambridge, 2013)
We report here computed spin-state energies and UV-Vis spectra for several transition metal complexes with a triazacyclononane ligand. Our results show that the spin ground-state is correctly obtained with either OPBE or ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...
Prediction of strong O-H/M hydrogen bonding between water and square-planar Ir and Rh complexes
(Royal Soc Chemistry, Cambridge, 2017)
Intermolecular OH/M interactions, between a water molecule and square-planar acac complexes ([M(acac)L-2]), with different types of L ligands (en, H2O, CO, CN-, and OH-) and different types of metal atoms (Ir(I), Rh(I), ...
Nitrate-assisted photocatalytic efficiency of defective Eu-doped Pr(OH)(3) nanostructures
(Royal Soc Chemistry, Cambridge, 2017)
Pr(OH)(3) one-dimensional nanostructures are a less studied member of lanthanide hydroxide nanostructures, which recently demonstrated an excellent adsorption capacity for organic pollutant removal from wastewater. In this ...
Chelated metal ions modulate the strength and geometry of stacking interactions: energies and potential energy surfaces for chelate-chelate stacking
(Royal Soc Chemistry, Cambridge, 2018)
Quantum chemical calculations were performed on model systems of stacking interactions between the acac type chelate rings of nickel, palladium, and platinum. CCSD(T)/CBS calculations showed that chelate-chelate stacking ...
Aliphatic-aromatic stacking interactions in cyclohexane-benzene are stronger than aromatic-aromatic interaction in the benzene dimer
(Royal Soc Chemistry, Cambridge, 2016)
Stacking interactions between cyclohexane and benzene were studied in crystal structures from the Cambridge Structural Database and by ab initio calculations. Calculated at the very accurate CCSD(T)/CBS level of theory, ...
General treatment of the multimode Jahn-Teller effect: study of fullerene cations
(Royal Soc Chemistry, Cambridge, 2013)
A general model for the analysis of the Adiabatic Potential Energy Surfaces (APES) of the molecules that are subject to the multimode Jahn-Teller effect is presented. The method utilizes the information obtained by DFT ...
The effect of two types of dibenzoannulation of pentalene on molecular energies and magnetically induced currents
(Royal Society of Chemistry, 2019)
The effect of two types of dibenzo-fusion of pentalene in the singlet and triplet states on its molecular energies and magnetically induced ring currents was examined via density functional calculations. The isomerization ...
Does aromaticity account for an enhanced thermodynamic stability? The case of monosubstituted azaborines and the stereoelectronic chameleonism of the NH2 group
(Royal Society of Chemistry, 2019)
This work was initiated by the increasing interest in BN/CC isosterism and by the long-lasting interest in the concepts of aromaticity and substituent effects. We have theoretically examined the aromaticity and stability ...
