Description
Polarized electronic spectra of trans-diacidobis (ethylenediamine )-
chromium(III) complexes were measured at liquid nitrogen temperature,
the diacido groups being aquochloro, aquobromo, bromochloro, bis(N, N-dimethylformamide), chloro(N, N-dimethyl£ormamide) and bromo(N, N-dimethylformamide). The quadrate components of the first two cubic
bands were polarized and assigned on the basis of predicted polarization
pattern for D4h vibronic mechanism for d^3 configuration. The higher energy intraconfigurational doublets were uncovered in most of the systems. The bis(N, N-dimethylformamide) complex showed two high-energy spin-forbidden bands at ~32,000 cm^-1 not previously observed in
the spectra of chromium(III) complexes. The ligand field and electron
correlation parameters were evaluated by fitting the observed band maxima with d^3 quadrate energy equations including full configuration interaction but neglecting spin-orbit perturbation. The parameters of these complexes
and of the other trans-diacidobis (ethylenediamine) systems obtained by
others were analysed in terms of the bonding nature of ligands.
