|Abstract:||N-(2-Carboxyphenyl)- and 2-amino- N-(2-carboxyphenyl)-benzamide complexes of Fe(III), Co(II), Ni( II), Cu(II), Ru(II), Ru(III), Rh(III) and Pd(II) have been prepared and characterized by physicochemical, thermal, spectral and magnetic methods. The coordination sites of ligands are confirmed by the absorptions in the IR and NMR spectra of diamagnetic complexes. Further, the geometry of the complexes has been established by electronic spectra, ESR studies of paramagnetic Ru(III) and Cu (II) complexes and Mossbauer spectra of Fe(III) complexes. N-(2-Carboxyphenyl)-benzamide is found to be a uninegative bidentate ligand coordinating through carboxylic oxygen and amide nitrogen while 2-aniino-N-(carboxyphenyl)-benzamide has been a tridentate ligand in all its complexes except in the case of Ru(II), in which it coordinates through amine and amide nitrogen atoms only.|
