| Abstract | ||
| A new multidentate ligand [ bis-1,4-( sodium thioglycolate ) butane] (L) was prepared from the reaction between 1,4-diclorobutane and disodiumthioglycolate in ethanol , and their complexes have the general formula [M2(L)2] and [M4(L)2Cl4] where (M=Co ( II), Ni (II), Cu (II) and Zn(II)) were prepared through direct reaction of the above ligand with CoCl2.6H2O , NiCl2.6H2O , CuCl2.2H2O and ZnCl2 respectively in (2:2) and (2:4 ) ligand to metal molar ratio. The prepared complexes were characterized by their metal contents, infrared , ultraviolet visible spectra , magnetic measurements and conductivity measurements while the ligand was characterized by elemental analysis. The electronic spectra and the magnetic moment measurements indicate that some of the complexes have square planar geometry while the other contain tetrahedral geometry. | ||
