A series of sulfoxides of the structures MenX3-nSn(CH2)3SOC2H 5 and MenX3-nSn(CH2)3SOC6H 5 (X = Cl or Br; n = 1-3) and sulfones MenX3-nSn(CH2)3SO2C 2H5 (X = Cl or Br; n = 1-3) have been prepared and characterized. 1H, 13C, and 119Sn NMR and IR studies were carried out. These showed that the sulfoxides with n = 1 or 2 are cyclic species with S-O → Sn coordination. The sulfones in chloroform showed evidence of intramolecularly coordinated species in equilibrium with acyclic species. Only the acyclic species were present in acetonitrile which presumably coordinates more strongly to the tin than does the sulfonyl group.
