The Synthesis of New bis(Amino-p-nitro-phenylglyoximes) and Their Polymeric Complexes with Cu(II), Ni(II), and Co(II)

Abstract

In this study, five new bis(amino-p-nitrophenylglyoximes), 1,4-phenylene bis(amino-p-nitrophenylglyoxime), 1,1′-biphenyl-4,4′-bis(amino-p-nitrophenylglyoxime), 1,1′-diphenyloxy-4,4′-bis(amino-p-nitrophenylglyoxime), 1,1′-diphenylmethlene-4,4′-bis(amino-p-nitrophenylglyoxime) and 1,1′-diphenylethylene-4,4′-bis(amino-p-nitrophenylglyoxime) have been synthesized from anti-p-nitrochlorophenylglyoxime and the corresponding aromatic diamines. Their polymeric complexes with Cu(II), Ni(II) and Co(II) have been obtained. The Cu(II) and Ni(II) complexes of these ligands are square-planar while the Co(II) complexes are octahedral with water molecules as axial ligands. ¹H-NMR, IR and elemental analyses data of the complexes and ligands are given.
