Synthesis and Characterization of Binuclear Complexes of Some Transition Metal in Addition to Zinc with bis (2-pyridoyl –6– carboxylic acid) thiourea ligand.

Abstract

A new complexes of Fe(II), Co (II), Ni (II), Cu (II) and Zn (II) were synthesized with new Tridentete ligand L= bis (2 pyridoyl –6– carboxylic acid) thiourea in 2:1 and 2:2 Metal : ligand molar ratios.The resulting complexes were of general formula [M2(L) Cl4] and [M2(L) 2 Cl4]. All complexes were characterized physiochemical with spectral methods by IR , UV –Visible . Two types of structures were suggested square planner and binuclear octahedral .
