... which is typical for high-spin tetracoordinated complexes of nickel. The calculations on quintet PES have resulted to the structure 26, destabilized relative to planar structure 24 on 5.8 kcal/mol. The spin density distribution in structure 26 shows the localization of two unpaired electrons on meta ...

... Another stabilizing factor is the polarizability (opposed to polarity) of an element in the acidic site. This term means the ability of the electrons to respond to a changing electric field, as a result of its interaction with solvent or with other polar reagents. Relative polarizability increases ...
