Synthesis and Characterization of Some New Metals Complexes of [N-( 4-chlorobenzoyl amino )-thioxomethyl] Anthranilic Acid (CBA)

Abstract

A new ligand [N-(4-chloro benzoyl amino)-thioxo methyl] anthranilic acid(CBA) was synthesized by reaction of 4chlorobenzoyl isothiocyanate with anthranilicacid by using acetone as a solvent , The ligand was characterized by elementalanalysis ,FT-IR,and13C, 1H-NMR spectra, some transition metals complexes of thisligand was prepared and characterized by FT-IR, UV-Visible spectra , conductivitymeasurements , magnetic susceptibility , atomic absorption and molar ratio ( M : L ).From results obtained ,the following formula [ M (CBA )2 ] where M+2 = Mn, Co ,Ni , Cu , Pd , Zn , Cd ,and Hg , the proposed molecular structure for thesecomplexes as tetrahedral geometry except copper and palladium complexes arehave square planer geometry .
