    A New Polydentate Ligand Aand it’s Cu (II) Complex – Synthesis and Characterization
    (Addis Ababa Universty, 2007-08) W/Tsadik, Desta; Chebude, Yonas (PhD)
    Dinuclear Copper (II) complex of a bis-chelating 4,6 – Bis{[((imidazo-5-yl) methyl) hydrazo] ethyl }-benzene-1,3-diol was synthesized and characterized by using conductivity, magnetic susceptibility measurement, IR and UV-VIS spectra. BIMHEBD was synthesized by the condensation of 2, 4-dihydroxy-5-acetylacetophenone dihydrazone (DAAD) with 4(5) – imidazo carboxo aldehyde. The ligand behaves as dibasic bis-tridentate chelating system through ONN-ONN donor sequence. Subnormal magnetic moment of the complex indicates the possibility of antiferomagnetic interaction through a possible superexchange mechanism.
