Bis(thioether)silanes: Synthesis and characterization of tin(IV) complexes with new dithioether ligands

Abstract

The bis(thioether)silanes Me₂Si(CH₂SR)₂ (abbreviated Bts^R, where R = Me or Prⁱ), the first two members of a new family of bidentate thioether ligands, have been readily prepared and fully characterized. The tin(IV) tetrahalide derivatives (Bts^R)SnX₄ (X = Cl, Br), which comprise the first four metal coordination complexes of these new sulfur-donor ligands, have also been isolated, and the X-ray structure of the tetrabromide derivative (Bts^Me)SnBr₄ confirms the chelating nature of the dithioether.
