✦ Synopsis

Crystal structures of five tin(IV) complexes containing the tetrahydrothiophene-1-oxide ligand, C 4 H 8 SO, TMSO, with Sn--O interactions, are described. They are trigonal bipyramidal Ph 2 SnCl 2 (TMSO), with TMSO and Cl in axial sites, and the octahedral complexes, Ph 2 SnCl 2 (TMSO) 2 and SnX 4 (TMSO) 2 , where X ¼ Br or Cl. In the octahedral complexes, the TMSO ligands are cis to one another and are trans to the halides. The SnCl 4 (TMSO) 2 complex has been obtained in two crystalline forms, one orthorhombic and isostructural with SnBr 4 (TMSO) 2 , and the other triclinic. Strengths of the interactions of the tin halides with dimethyl sulfoxide, (DMSO), and TMSO ligands are compared.
