Abstract: 2-Methoxy benzaldehyde isonicotinoylhydrazone (MBINH), and its iron (II), cobalt (II) and nickel (II) complexes have been synthesized and characterized based on physico chemical properties, Electronic and IR spectra. The IR observations suggest that the ligands have coordinated through azomethine nitrogen atom, oxygen atom and through methoxy groups. The invitro antibacterial activity of complexes against Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Bacillus subtilis bacteria was screened and compared to the activity of the free ligand, the antibacterial activity of iron complex is active than Co & Ni complexes.
