The DFT study of isomerism of Ni2+ complexes
Abstract
The
impact of intramolecular steric hindrance on the cis-trans isomerism of the
square Ni2+ complexes with the [2S,2N] coordination centers was
modeled at the level of density functional theory (DFT). The non-hindered
complexes exist as trans isomers; with the grow of the substituents at the N
atoms the complex molecule transforms to the cis isomer and further to the
tetrahedral geometry. Statistical analysis of the crystal structures from
Cambridge structural database confirms this conclusion.
