THE SYNTHESIS OF NEW BIS(AMINO-R-GLYOXIMES) AND POLYAMIDOXIME THEIR POLYMERIC METAL-COMPLEXES

In this study, new bis(amino-R-glyoximes) and polyamidoxime, 3,3'-dime thyl-1,1'-biphenyl-4,4'-bis (aminoglyoxime) L1, methyl-1,1'-biphenyl-4 ,4'-bis(aminophenylglyoxime) L2, thyl-1,1'-biphenyl-4,4'-bis(amino-p-t olylglyoxime) L3 and ly-3,3'-dimethyl-1,1'-biphenyl-4,4'-diaminodioxim e L4, have been synthesized from anti-chloroglyoxime, anti-phenylchlor oglyoxime, anti-p-tolylchloroglyoxime, anti-dichloroglyoxime and (o-to lidine) aromatic diamines. Their polymeric complexes with Ni(II), Cu(I I) and Co(II) have been obtained. The Ni(II) and Cu(II) complexes of t hese ligands are proposed to be square-planar while the Co(II) complex es are octahedral with water molecules as axial ligands. H-1-NMR, IR s pectra and elemental analyses data are given.
