Spectral and Magnetic Studies of Cobalt(II), Nickle(II), Copper(II), Zinc(II) and Silver(I) Complexes with 4-(2-Thiazolyl) Thiosemicarbazide

Abstract

Paramagnetic cobalt(II), nickel(II), copper(II) and diamagnetic zinc(II) and Ag(I) complexes of 4-(2-thiazolyl) thiosemicarbazide (L) of the compositions MLCl₂ [M ═ Co(II), Ni(II) and Cu(II)], ZnL₂Cl₂ and AgLNO₃, have been prepared and characterized by spectral (ir, ¹⁴N nmr and esr for CuLCl₂ only) and magnetic studies as well as by elemental analyses. All of the complexes except Ag(I) have octahedral coordination whereas Ag(I) has tetrahedral arrangement of ligand around it.
