Abstract

A new crystal of, [Cu (OH2)2 (en)2] 4-oxidobenzoate and [Cu(OH2)2 (en)2] (3,5-dinitrobenzoate)2 Where (en = ethylenediamine) have- been synthesize, and the resulting complexes has been analyzed on the base of CHN analyses, IR spectral, Electronic spectra,  single- crystal X-ray- diffraction method and magnetic susceptibility. In both complexes cations have a distorted octahedral CuN4O2 around copper (II), surrounded by two molecules of ethylenediamine and two water molecules. The cations [Cu (en) 2(OH2)2]2+ of both complexes are associated to carboxylate anions by hydrogen bonding in addition to electrostatic forces.
