Abstract

The mixed ligand complexes of the type [ML₁L₂]Cl₂, where M=Mn(II), Fe(III),Co(II), Ni(II), Cu(II)L₁=pyruvic acid semicarbazone (PYSC) L₂= acetone semicarbazone (ACSC). These complexes have been synthesized by the reactions of metal chlorides with two different semicarbazone in 1:1:1 molar ratios. The resulting products have been characterized on the basis of elemental analysis, magnetic measurement, IR and electronic spectra, conductivity measurement, thermalanalysis, antimicrobialactivities. The metal complexes show ratio 1:1:1 with metal, ligand L₁ and ligand L₂. The ligands are bonded through oxygen and nitrogen to metal ion.
