COMPLEXES OF SOME GROUP-IV METAL-HALIDES, ACETATE AND ORGANOTINS WITHTHIOACETAMIDE

Reactions of silicon tetrachloride, titanium tetrachloride, zirconium tetrachloride, tin tetrachloride, trimethyltin chloride, dibutyltin di acetate and tributyltin chloride with thioacetamide led to the formati on of non-ionic and stable complexes of the formula MCl4.(TA)(2) and S nX4.(TA)(2) (where M = Si, Ti, Zr or Sn and X = Cl and CH3, CH3COO and C4H9 or C4H9 and Cl, and TA = thioacetamide). These complexes were ch aracterized by melting/decomposition point determinations, analytical data, conductivity measurements and spectroscopic (UV and IR) studies. An octahedral geometry is proposed for all the complexes and coordina tion through sulphur is predicted.
