Abstract: The derived bidentate schiff base (N-(2-((E)-4 hydroxy benzylidene) amino) phenyl)-1-(p tolyl) methenamine) by condensing 4-Hydroxy Benzaldehyde and o-Phenylenediamine have been synthesized. The above synthesized Schiff base forms stable coordinated metal complexes, using salts of Rhodium, Platinum and Gold. The synthesized Schiff base and metal complexes were characterized by U.V, FTIR, 1H-NMR and the percentage of elemental detections were determined by CHNS analyzer. The thermal stability of metal complexes was studied using TGA indicating the synthesized metal complexes up to 450- 650 0C. The characterization study confirms the formation of stable octahedral Rh (III) complex whereas Pt (II) and Au (III) complexes shows square planar structures. The crystal systems of the metal complexes were studied X-ray diffractometer. Further the comparative antimicrobial activities of the Schiff base and corresponding metal complexes have been studied.
