Two complexes [Mn(HL)3(CH3OH)](ClO4)2 (1), [Zn(HL)2(H2O)2](ClO4)2 (2), where HL is a Schiff base ligand 2-[(4-methylphenylimino)methyl]-6-methoxyphenol (C15H15NO2) derived from condensation of o-vanillin (2-hydroxy-3-methoxybenzaldehyde) with p-toluidine. They were characterized by elemental analysis, molar conductance, FTIR,UV-Vis, 1H NMR spectra. The structures of complexes were deterimend by X-ray diffraction single-crystal structure analyses. The Schiff base ligand and it's complexes have been tested in vitro to evaluate their antibacterial activity against bacteria, viz., Escherichia Coli, Staphylococcus Aureus and Bacillus Subtilis. It has been fond that the Zn(Ⅱ)complex has higher activity than the corresponding free Schiff base ligand and Mn (Ⅱ) complex against the same bacteria. CCDC: 692600, 1; 692601, 2.
