The synthesis of four new bis(amino-p-chlorophenylglyoximes) and their polymeric complexes

Abstract

In this study, four new bis(amino-p-chlorophenylglyoximes), 1,2-phenylenebis(amino-p-chlorophenylglyoxime) L1H2, 1,5-naphthylenebis(amino-p-chlorophenylglyoxime) L2H2, 3,4-tolylenebis(amino-p-chlorophenylglyoxime) L3H2, and 2,6-pyridylbis(amino-p-chlorophlenylglyoxime) L4H2, have been synthesized from anti-p-chlorophenylchloroglyoxime and the corresponding aromatic diamines. Their polymeric complexes with Ni(II), Co(II) and Cu(II) have been prepered. The Ni(II) and Cu(II) complexes of these ligands have been found to be square-planar, while the Co(II) complexes are octahedral with water molecules as axial ligands. 1H NMR, AAS, IR, magnetic susceptibility and elemental analytical data of the complexes and ligands are discussed.
