Abstract

A series of few mixed ligand complexes of, manganese(II),iron(II),cobalt(II), nickel(II), zinc (II) and cadmium(II), have been synthesized with The mixed ligand complexes have been characterized by, spectroscopic spectral measurements (FT-IR, U.V- Vis), molar conductance, magnetic measurements, and chloride content (Mohr Method) , metal contents of the complexes were determined by Atomic Absorption . The results suggest that the Mn(II), Fe(II), Co(II), Ni(II), Zn(II), and Cd(II) have distorted tetrahedral geometry . The following general formulae were proposed for the prepared complexes:[M (pro) (Thr)] , where pro- = C5H8NO2 - Thr= C4H9NO2 - , M+2 = Mn(II), Fe(II), Co(II), Ni(II), Zn(II), and Cd(II). Molar conductance of a 10−3 M solution in (DMF) indicates that all the complexes are non-electrolytes.
