Abstract

Palladium(II) complexes with nine carboxy amide ligands viz. 4-(2-acetylhydrazino)-4-oxobut-2-enoicacid (AOBEH), 4-(2-acetylhydrazino)-4-oxobutanoicacid (AOBAH),  2-[(2-acetylhydraz ino)carbonyl]benzoicacid (AHCBH), 4-[(2-cyanophenyl)amino]-4-oxobut-2-enoic acid(COBEH) 4-[(2-cyanophenyl)amino]-4-oxobutanoicacid(COBAH),2-{[(2-cyanophenyl)amino]carbonyl} benzoicacid (CACBH), 4-(1H-benzimidazol-2-ylamino)-4-oxobut-2-enoicacid (BOBEH), 4-(1H-benzimidazol-2-ylamino)-4-oxobutanoicacid (BOBAH) and 2-[(1H-benzimidazol-2-ylamino)car bonyl]benzoicacid (BYCBH) have been synthesized and characterized by elemental analysis, magnetic moments, molar conductivity, thermal studies, infrared, 1H NMR and electronic spectral data.
