The IR spectral data taken was suggested the involvement of oxygen and azomethane nitrogen in coordination to the central metal ion. On the basis of spectral studies, an octahedral geometry had been assigned for Ni(II) complexes but a tetragonal geometry for Cu(II) complexes. The free ligand and its metal complexes had been tested in vitro against a number of microorganisms in order to assess their antimicrobial properties.
