NITROGEN AND SULFUR BONDED ORGANOSILICON(IV) COMPLEXES - SYNTHETIC AND SPECTROSCOPIC ASPECTS

Some tri-, di- and monoorganosilicon(lv) complexes of salicylaldehyde thiosemicarbazone have been synthesized by the reactions of the corres ponding tri-, di- and monoorganosilicon(IV) chlorides with the sodium salt of salicylaldehyde thiosemicarbazone in different stoichiometric ratios. The compounds are yellow coloured solids, soluble in common or ganic solvents and are monomeric in CHCl3 solution. These derivatives have been characterized by elemental analyses, molecular weights, cond uctivity measurements and spectral (IR, H-1, C-13 and Si-29 NMR) studi es. The complexation occurs via the thiol sulfur, and the imino nitrog en atom.
