Two new peroxo complexes of Cu(II) and Ni(II) ion containing Schiff base (SB) were synthesized and characterized by TLC, Elemental analyses, conductivity, magnetic moment measurements, UV-Vis. and IR and ESI-MS spectral studies. The Schiff base ligand derived from cinnamaldehyde and o-aminophenol participated in complexation through a single pot reaction. IR spectra showed that the Schiff base ligand coordinated to the metal ion through nitrogen of azomethine group and oxygen of hydroxyl group & peroxo group (O-O). Magnetic moment value coupled with electronic spectral data suggested a square planar geometry for both the complexes. The molar conductance values indicated the non-electrolytic nature of the complexes. Antibacterial activity of the complexes was tested against four pathogenic bacteria, two Gram-positive Staphylococcus aureus & Bacillus cereus and two Gram-negative Escherichia coli & Shigella dysenteriae with Kanamycin (K-30) standard. The result shows that Cu(II) complex exhibited more potential antibacterial activity than the Ni(II) complex against all the tested organisms. |
