Synthesis, characterization and antimicrobial studies on nickel (II) and copper (II) complexes of 2N2O2 donor schiff base

The ligand and its complexes of Ni(II) and Cu(II) were investigated in terms of synthesis, elemental analysis, infrared; electronic spectra, thermal analysis and antibacterial and antifungal activities. The results shows that the complexes are formed with 2M:L (2Metal:1ligand) molar ratio. Tetradentate Schiff base ligand with 2N2O2 donor atoms is coordinated to Ni(II) and Cu(II) ions to form the corresponding complex. Antibacterial and antifungal activity of the synthesized ligand and its complexes was tested against selected pathogenic bacteria and fungi. Cu2L complex showed more antifungal activity than (Ni2L) analogous. The complexes are possessed microorganism activities higher than that of the free ligand
