Synthesis and Characterization of Some Metal Complexes of [4-chloro-N- 1,5-dimethy l-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl(benzamide)

Abstract

AbstractA new ligand [4-chloro-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarb amothioyl) benzamide] (CAP) was synthesized by reaction of P-ChloroBenzoyl isothio cyanate with 4-aminoantipyrine,The ligand was characterized by micro elemental analysis C.H.N.S.,FT-IR,UV-Vis and1H-13CNMR spectra, some transition metals complex of this ligand were prepared and characterized by FT-IR, UV-Vis spectra, conductivity measurements, magnetic susceptibility and atomic absorption. From the obtained results the molecular formula of all prepared complexes were [M(CAP)2(H2O)2]Cl2(M+2 =Mn, Co, Ni, Cu, Zn, Cd and Hg),the proposed geometrical structure for all complexes were octahedral.Key Word :4-Aminoantipyrine, P-ChloroBenzoyl isothiocyanate, complexes.
