摘要:
Complexes of N-anthranilamido-N'-benzoylthiocarbamide (H(2)ABTC) with Cr(III), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and UO2(VI) have been synthesized and characterized on the basis of elemental analyses, molar conductivities, spectral (IR and visible) and magnetic studies. IR spectral data show that the ligand behaves in a neutral bidentate, mononegative bidentate or tridentate and binegative tridentate or tetradentate manner. All the complexes are non-electrolytes. Different stereochemistries are proposed for the Cr(III), Mn(II), Co(II), Ni(II) and Cu(II) complexes according to the data of magnetic and electronic spectral measurements. IR data indicate that the carbonyl oxygen of the benzoyl moiety is the backbone of the chelating agent in all the complexes.
