| Abstract Metal complexes of general formula [M(L)2]Cl2 and [M(L)2], L=L1, L2, L3 have been prepared where M is Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), L1 is (Z)-3- (4-methoxyphenylimino) indolin-2-one, L2 is (Z) -1- ((4-methoxyphenylimino) methyl) naphthalene-2-ol, L3 is (Z)-2-(4-methoxyphenylimino) -2-phenylethanol. The complexes which have the molar ratio of 1:2 (metal to ligand). The complexes were characterized by elemental analyses, magnetic and conductance measurements infrared absorpation spectra and electronic spectra. IR spectra showed that the nitrogen of the azomethine group, carbonyl oxygen of L1 or the oxygen hydroxy group for the L2 and L3 take part in coordination. Magnetic susceptibility measurements and electronic spectra studies suggested a tetrahedral structure for all complexes. Conductance measurements indicating the 1:2 electrolytic nature for L1 and non electrolyte for L2 and L3. The biological activity testes indicate that most of the prepared complexes posses high ability to inhibit growth Staphylococcus aureus and Escherichia coli bacteria. | ||
