MIXED LIGAND COMPLEXES OF THALLIUM(Ⅰ) METAL CHELATES OF SOME ORGANIC ACIDS WITH HIPPURIC ACID

摘要

Some nobel mixed ligand complexes of the general formula, ML.HL', where M = TI (Ⅰ); L = deprotonated o-nitrophenol (ONP), 2, 4-dinitro-phenol(DNP), 2, 4, 6-trinitro-phenol (TNP), 1-nitroso-2-naphthol (1N2N), 8-hydroxyquinoline (8HQ) or o-nitrobenzoic acid (ONBA) and HL' = hippuric acid, have been synthesized, and characterized by elemental analysis, molar conductance measurements, infrared and electronic spectral studies. Their Infrared spectra suggest coordination of the hippuric acid with thallium metal through the nitrogen atoms of -NH_2(amino) group and oxygen atom of -COOH(carboxyl) group.
