| Abstract | ||
| The reaction between 3,3-,4,4– tetraaminobiphenyl and o-hydroxy benzaldehyde in 1:4 molar ratio affords a novel tetrabasic octadentate Schiff base (Fig(1) ) . Its reaction with Ni(OAc)2 in 1:2 molar ratio. Leads to the formation of dinuclear complexes of the general formula [Ni2L] and the latter. reacts with the metal halide MX2 ( M= , Ni, Cu, X=Cl or Br ) in 1:2 molar ratio to form tetranuclear complexes of the general formula [ Ni2LM2X4], M=Ni,Cu . The coordination of the Schiff base in the dinuclear complexes seems to occur via N- azomethine and the deprotonated OH groups , while the further coordination in the tetranuclear complexes seems to take place via the lone pair of electrons available on the oxygen atoms . The structural features of the chelates have been confirmed by elemental analysis , IR ,Uv –vis and magnetic measurement .The compounds have been prepared at the room lab Temperature. | ||
