Abstract

The mixed ligand complexes of the type Cr(L1L2)Cl3Where L1=pyruvic acid semicarbazone and L2= acetone semicarbazone, benzaldehyde semicarbazone, acetophenone semicarbazone, cyclohexanone semicarbazone have been synthesized by the reaction of chromium chloride with two ligands L1 and L2 in the ratio 1:1:1 molar ratio. The resulting complexes have been characterized on the basis of elemental analysis, magnetic measurement, IR and UV spectral analysis, conductivity measurement, thermal analysis, antimicrobial activities. Analysis of results reviles that the complexes shows octahedral geometry, electrolytic nature and having more antimicrobial activity than the ligands. The ligands are bonded through oxygen and nitrogen.

Keywords: The mixed ligand benzaldehyde semicarbazone, oxygen and nitrogen.
