Some reactions of tin oxide chloride and titanium oxide chloride

Abstract

Some reactions of tin oxide chloride with pyridine and with tetrahydrothiophen are reported, and it is suggested that products are normally of the form SnO₂ and SnCl₄,L₂. Reaction of tin oxide chloride or titanium oxide chloride with acetylacetone appears to lead to the known compounds MCl₂(acac)₂(where Hacac = acetylacetone, M = Sn or Ti). Several preparations of “TiO(acac)₂” did not (with the present authors) lead to a monomeric species. The nature of the cation TiOCl₄^2– is discussed as is the characterisation of “metal–oxygen double bonds” using vibrational spectroscopy.
