DIVALENT TRANSITION-METAL COMPLEXES WITH SOME N-PHENYL, N'-HETEROAROMATIC THIOUREA DERIVATIVES

The complexes of Mn(II), Fe(II) and Zn(II) with N-phenyl,N'-(2-thiazol yl)thiourea and N-phenyl, N'-(2-primidyl)thiourea have been described. The complexes were found to have the formulas [Mn(L)(2)Cl-2], [Fe(L)( 2)SO4]. 2H(2)O and [Zn(L)2]SO4 . 3H(2)O, where M = Mn-II or Fe-II and L = thiourea derivative. Characterization of the complexes has been ac complished by elemental analysis, electronic and IR spectra, conductiv ity measurements as well as thermal analysis. The thiourea derivatives used were found to act as neutral bidentate ligands, and the complexe s assume a distorted octahedral or tetrahedral stereochemical configur ation.
