MustafeaChemistry Department, College of Sciences, University of Kirkuk, Kirkuk, IraqChemistry Department, College of Education for Pure Sciences, University of Kirkuk, Kirkuk, IraqThis study involved the preparation of a New Complexes Schiff bases (L): 2-((3-ethoxy-4-hydroxybenzylidene) amino) benzoic acid, made using the identical precursor for the electron acceptor (A): The molar ratio of the reaction between 3-ethoxy-4-hydroxy benzaldehyde and electron donors (Ds) anthranilic acid was 1:1. The Schiff base ligands were used to react the salts of the Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes. The complexes Measurements of molar conductivity are not electrolytic. CHN analysis of the elements, FTIR spectra, mass spectra, 1HNMR and 13CNMR were used to characterize the Schiff base ligand (L) and the same complexes samples in order to corroborate the molecular structures. The molecular structures determine the optical and biological activity. The tetrahedral geometry surrounding both of the metals and the curved planar geometry around Cu (II).
