New Schiff base derived from 3-aminophenol and 2-hydroxy-3-methoxy benzaldehyde in ethanolic media and its complexes with Co(II), Mn(II), Ni(II), Cu(II) and Zn(II) have been prepared. These complexes are characterised by IR, 1H NMR,UV, Elemental analysis and Molar conductance measurements. From the analytical and spectral data, the stoichiometry has been found to be 1:2 for all the complexes. The Schiff base ligand and the complexes have been screened for antimicrobial activity by disc diffusion technique. The activity data showed that the metal complexes have more antifungal and antibacterial activity than the parent ligand.
