Abstract: The bis(thioether)silanes Me2Si(CH2SR)2 (abbreviated BtsR, 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 (BtsR)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 (BtsMe)SnBr4 confirms the chelating nature of the dithioether.
