Triphenyltelluronium Halo (mixed) Titanates(IV)

Abstract

The paper reports the synthesis and properties of triphenyltelluronium halo (mixed) titanates (IV)º. 1 : 1. Ph₃TeX.TiX´₄ and 2 : 1, 2Ph₃TeX.TiX´₄ (where X,X´═Cl, Br, I) type products are obtained by reactions of Ph₃TeX with TiX´₄. Conductivity, molecular weight determinations and ¹H nmr are consistent with their dissociation in dilute solution as Ph₃Te⁺ and TiX´₄X^– or Ph₃Te⁺ and TiX´₄X²₂– units. The absence of Te–Ti and Te–X vibrations in the far i.r. spectra of these compounds reflects the transfer of halogen atom from Ph₃ TeX to TiX´₄ thus resulting in the formation of halo (mixed) titanate (IV) ions.
