Studies on coordination Compounds of Co(II), Cu(II), Ni(II), Cd(II), Zn(II) 3d-Transition Metal Ions with Acylthiosemicarbazide

Abstract

The synthesis of some coordination compounds of N1-[4-(4-brgmophenylsulfonyl) benzoyll-N4-(4-methylphenyl) thiosemicarbazide (BrATS) with CuC12, Cu (CH3COO)2, Cu(SCN)2, Co(CH3COO)2, Ni(CH3COO)2, Cd(CH3COO)2 and ZnC12 are described. The characterization of the complexes has been performed with the help of various physicoOchemical techniques viz., IR, EPR, electronic spectroscopy, magnetic moments, thermogravimetric analysis, molar conductance and elemental analysis; Experimental data confirm the molar combination ratio M:L =1:1 or 1:2 for the synthesized complexes. Room temperature ESR spectra of Cu(II) complexes yield (g) values characteristic of distorted octahedral and square-planar geometry.
