The synthesis and characterization of mixed ligand complexes of Fe (III) with tartaric acid/succinic acid and heterocyclic amines. These complexes were characterized on the basis of elemental analysis, conductometric, magnetic measurements, UV-vis, IR spectral studies. All the complexes were found electrolytic and paramagnetic in nature with high spin octahedral structure. The synthesized complexes showed moderate to strong antimicrobial activity.
