Synthesis and characterization of new complexes of copper (ii) and zinc (ii) a basis of schiff bases ligands n, n’-bis (diphenylmethylene) ethane- 1, 2-diamine (l1) and n, n’-bis (diphenylmethylene) benzene -1, 2-diamine (l2)

A new series of copper (II) and zinc (II) Schiff bases complexes containing the bidentate ligands N, N'-bis (diphenylmethylene) ethane-1, 2-diamine (L1) and N, N'-bis (diphenyl methylene) benzene-1, 2-diamine (L2) was prepared by the condensation of the ethylenediamine, or the orthophénylènediamine on benzophenone in ethanol at reflux. The Schiff base ligands and their corresponding complexes have been identified by IR spectroscopy, 1H NMR, 13C NMR and by ESI MS spectrometry. The copper (II) and zinc (II) complexes obtained have a octahedral geometry; the metal cations are linked to the four nitrogen atoms of the imine grouping (C=N).
