Ea. Bernhardt et Pn. Komozin, G-TENSOR THEORY FOR STRONGLY DISTORTED OCTAHEDRAL LOW-SPIN D(5) COMPLEXES, Journal of structural chemistry, 35(1), 1994, pp. 27-42
Using the crystal-field theory (CFT), we derive equations for the low-
spin d5 configuration in the case of an arbitrary ligand field includi
ng the configuration interaction correction. Experimental ESR and elec
tronic absorption spectral data of some octahedral Ru(III) and Os(III)
complexes with a strong tetragonal distortion are analyzed. It is sho
wn that the contribution of the spin-orbit term of the configuration i
nteraction may be considerably suppressed due to the strong covalency
of the sigma-bond.
