Abstract

The mixed ligand complexes of the type [FeL1L2]Cl3. Where L1=Pyruvic acid semicarbazone L2= semicarbazone of acetone, acetophenone, Benzaldehyde, cyclohexanone, salicylaldehyde semicarbazone, O-hydroxy acetophanone. These complexes have been synthesized, by the reactions of metal chlorides with two different semicarbazones in 1:1:1 molar ratio. The resulting products have been characterized on the basis 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 L1 and ligand L2. The ligands are bonded through oxygen and nitrogen to metal ion.

Keywords: Mixed ligand complexes, semicarbazone, pyruvic acid, acetone, acetophenone, Benzaldehyde, cyclohexanone, O-hydroxy acetophanone, thermal analysis, antimicrobial analysis.
