The mixed ligand complexes of the type [ML1L2]Cl2. Where M=Co(II), AND L1=Pyruvic acid semicarbazone L2= Acetone semicarbazone, Acetophenone semicarbazone,Benz aldehyde
semicarbazone, Cyclohexanone semicarbazone, O-hydroxy
acetophenone semicarbazone have been synthesized, by the reactions
of metal chlorides with two different semicarbazones in 1:1:1 molar ratios. The resulting products have been characterized on the bas is of
elemental analysis, magnetic measurement, IR and Electronic spectra,
conductivity measurement, thermal analysis, antimicrobial activities.
The metal complexes show ratio 1:1:1 with metal, ligand L
1 and ligand L2.The ligands are bonded through oxygen and nitrogen to metal ion.
