Abstract

The UV-VIS and EPR spectra of solutions of NiII (4-DMAB) in 10 solvents with donor number (DN) from 0.1 to 38.81 have been recorded. The changes in the spectra are in terms of a change in symmetry of the NiII (4-DMAB) complex on increase in donor number of the solvent. The symmetry change is from square planar to rhombic bipyramidal with correspoding change in electronic configuration of the nickel ion from d2z2 to d1z2, d1x2- ...
