Synthesis and characterization of new metal ions Mn (II), Co (II), Ni (II), Cu (II), Zn (II) and Cd (II) complexes with (E)-1-(1-(furan-2-yl)ethylideneamino)anthracene-9,10-dione ligand and evaluation of their biological activities

Metal complexes of the general formula [MLCl2] and [ML2Cl2], L= (E)-1-(1-(furan-2- yl)ethylideneamino)anthracene-9,10-dione and M = Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) in (1:1) and (1:2) metal to ligand malor ratio have been prepared and characterized by molar conductance, magnetic measurement, FT- IR, UV-visible spectral studies and metal content analysis, Conductivity measurements indicates that all complexes were non electrolytes and the ligand. Schiff base behaves as a bidentate chelating ligand. Magnetic moment and electronic spectra indicates that the complexes have either tetrahedral or octahedral geometry. Beside of, the biological activity testes indicate that some of the prepared complexes posses ability to inhibit growth Staphylococcus aureus and Escherichia coli bacteria.
