Abstract : The synthesis and study by X-ray crystallography and magnetic methods of two mononuclear and one binuclear copper(II) compounds with 2- or 4-aminobenzoate (2amb, 4amb) and 2,2’-bipyridine (bpy) is reported. In 3b the dimeric cation, [Cu2 (bpy)2(4amb)2(H2O)(CH3OH)]2+, possesses chelating diimine and bridging benzoate with the copper(II) centers in a square pyramidal environment which is asymmetrically filled by one water and one methanol molecule. The compound is a typical antiferromagentically coupled complex with a -2J value calculated as 91.0 cm-1. The monomeric compound of 2-aminobenzoate presents an octahedral metal environment with a chelating benzoate and some water molecules in the crystal lattice, while for the corresponding one with 4-aminobenzoate reveals an almost trigonal bipyramidal copper(II) centre with the monodentate carboxylate occupying the axial position. In the lattice of the isolated compound there exist some neutral molecules of the acid besides water molecules. Keywords - Copper(II), 2,2’-Bipyridine, Aminobenzoic Acid, Crystal Structure, Magnetic Exchange, EPR Spectra
