Abstract
Ternary complexes of Cr(III) with l-histidine monohydrochloride and various diols of the type MAB, MA2B and MAB2 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 MA2B type species as compared to MAB and MAB2 species. Values of nephelauxetic ratio β55 (for spin forbidden band) were found to be more than β35 (for spin allowed transition).
