Synthesis and Characterization of some Complexes of Mn(II),Fe(II), Co(II), Ni(II), Cu(II) and Zn(II)withBis-(2, 3-Dimethoxybenzylidene) thiosemicarbazone

Abstract

A number of new complexes of the general formulaes [ML2Cl2] and
[ML₂(bip)]Cl₂ {where L= bis-(2,3-Dimethoxybenzylidene)thiosemcarbazone ; M=
Mn(II), Fe(II),Co(II), Ni(II), Cu(II) and Zn(II),bip = bipyridyl}were prepared and
characterized by molar conductance, magnetic properties, infrared, electronic
spectra,metal contents, and CHN analysis. The electronic spectra study and magnetic
moments measurements indicated that the Mn(II), Fe(II), Co(II), Ni(II), Cu(II)and
Zn(II)complexes have an octahedral geometry.
