SYNTHESIS AND CHARACTERIZATION OF COPPER(II) COMPLEX CONTAINING 2,2'-DIPYRIDYLBENZAMIDE

A new copper complex containing 2,2'-dipyridylbenzamide(dpba), Cu(dpba )(NO3)(2)(CH3CN), has been synthesized and characterized. The crystal structure has been determined. Crystal data: space group P2(1)2(1)2(1) , Z=8, a=13.911(3) Angstrom, b=16.813(3) Angstrom, c=18.932(3) Angstro m, V=4427.9(1) Angstrom(3) and R=0.0674 for 1716 reflections. The copp er environment is square pyramidal containing acetonitrile in axial si te. Spectroscopic properties has been characterized in solution state. The redox property of the Cu(dpba)(NO3)(2) complex is different from that of corresponding copper-dpa complex.
