Abstract
Ternary complexes of Cr(III) with L-histidine monohydrochloride and various diols of the type MAB, MA(2)B and MAB(2) were synthesized and characterized in the present study. The structural properties of complexes were derived from the elemental analysis and magnetic characterization. The elemental analysis and magnetic characterization indicated that they have the octahedral stereochemistry with three unpaired electrons. The values of Dq/B were of greater magnitude for MA(2)B type species as compared to MAB and MAB(2) species. Values of nephelauxetic ratio beta(55) (for spin forbidden band) were found to be more than beta(35) (for spin allowed transition).
