The mixed ligand complexes of the type [M(L1)(L2)]Cl2 (where M= Mn (II), Fe(III), Co(II), Ni(II) and Cu(II) and L1 = Acetophenone semicarbazone, L2=Acetone semicarbazone) have been synthesized by the reactions of metal chlorides with two different semicarbazone compounds in 1:1:1 molar ratios. The resulting complexes have been characterized on the basis of elemental analysis, magnetic measurement, IR and electronic spectra, conductivity measurement. The metal complexes shows ratio 1:1:1 with metal, ligand L1 and ligand L2.The ligands acts as bidentate ligands and are bonded through oxygen and nitrogen to metal ion. The two co-ordination positions are occupied by two water molecules. The complexes have octahedral structure.
