SYNTHESIS, CHARACTERISATION AND BIOLOGICAL STUDIES OF METAL COMPLEXES OF THE SCHIFF BASE {2-[FURAN-2-YL METHYLENEAMINO]PYRIDINE-3-OL}.

Five new complexes of Mn(II), Co(II) ), Ni(II), Cu(II)& Zn(II) with the Schiff base {2-[furan-2-yl methyleneamino]pyridine-3-ol} has been synthesized and characterized by elemental analyses, FT-IR, 1H-NMR, Electronic, ESR, Mass spectra, magnetic susceptibility and electrolytic conductance. The Schiff base acts as unianionic bidentate manner with all the metal ions. The metal Schiff base ratio is 1:1 in all complexes except in Ni(II) where it is 1:2. The antimicrobial activity of the Schiff base and selected complexes were studied. The result shows that complexes have comparable antibacterial activity with the ligand. The Schiff base and the Mn(II) complex were subjected to antioxidant study.
