A new ligand [N-(4-chloro benzoyl amino)-thioxo methyl] anthranilic acid
(CBA) was synthesized by reaction of 4chlorobenzoyl isothiocyanate with anthranilic
acid by using acetone as a solvent , The ligand was characterized by elemental
analysis ,FT-IR,and13C, 1H-NMR spectra, some transition metals complexes of this
ligand was prepared and characterized by FT-IR, UV-Visible spectra , conductivity
measurements , 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 these
complexes as tetrahedral geometry except copper and palladium complexes are
have square planer geometry . |
