Abstract :A series of new multidentate ligands (L1-L4), 1,1,2,2-tetrakis [2-(benzylthio)ethylthio]ethylene(L1),1,1,2,2-tetrakis [2-(o-tolylthio) ethylthio]) ethylene (L2) , 1,1,2,2-tetrakis [3-(p-chlorophenylthio) ethylthio] ethylene (L3) and 1,1,2,2-tetrakis [2-(o-aminophenylthio) ethylthio] ethyene (L4) were prepared from the reaction of equimolamar amount of (4-mercapto-2-thia-1-butyl benzene or o-methyl-4-mercapto-1-thia-1-butyl benzene or p-chloro-4-mercapto-1-thia-1-butyl benzene or o-amino-4-mercapto -1-thia-1-butyl benzene and KOH) with tetrachloroethylene in (4:4:1) molar ratio . Reaction of the above ligands with nickel (II) , palladium (II) and platinum (II) chloride salts gave the complexes of the general formulas : [M2(L)Cl4] and [Ni2(L)Cl2]Cl2 M=Ni(II) , Pd(II) and Pt(II) , L=L1-L4 . The synthesized ligands have been characterized on the basis of their elemental analysis , FTIR, 1H ,13C NMR , and their complexes were characterized by elemental analysis metal content, UV-Vis. spectroscopic technique ,conductivity measurements and magnetic measurements. On the basis of these studies, a four coordinate tetrahedral or square planar geometry around the metal ions in the complexes has been proposed.Keywords : Bulky substituted thioether, Ni(II), Pd(II), Pt(II) complexes, Square planar complexes
