Abstract
This research involves the preparation of new ligands 1,1,2,2- tetrakis (sodium acetate thio)ethylene(L1) and 1,1,2- tris(sodiumacetatethio) ethylene(L2), through the reaction of disodium thioglycolate) with tetra chloro ethylene or tri chloro ethylene in (1:4) or (1:3) moler ratio . Homodinucliar complexes of general formlu [M2(L1)] and [M2(L2)ClH2O] , when M= Co(II), Ni(II), Cu (II) and Zn(II) also mono nuclear complexes of general formula [M(L2)] . The prepared complexes were characterized using spectral method (UV/Visible/ IR) , metal content analysis , magnetic and atomic measurements . The spectral and magnetic measurement indicats that some complexes have tetrahedral or square planar complexes environtment .
Highlights
Coordination chemistry of metal - sulfur or oxygen compounds is a source of stimulation to many research workers, due to the fact that it possesses unique metal complexes of ligands containing sulfur or oxygen as donor atoms were studied by many workers
The films containing different concentration of complexes ranging from 0.1% to 0.5% by weights were produced by the same casting method from THF solvent [3].New cobalt (II) dithio curbazats with different mono and dinegative counter ions of general formula [Co(IN-DtzH)2] Xn, where (INDtzH= isonicotinoyl dithiocarbazic acid, X= Cl, Br, NO3, ClO4, CH3COO for n= 2 and X= SO4 and C2O4 for n=1) have been obtained
The prepared complexes have been investigated by elemental analysis UV, IR and magnetic measure mentswere studied by Kalia etal [4].The synthesis and structural characterization of a novel in(III) complexes are described
