Iodine tris(trifluoromethanesulfonate), I(OSO2CF3)3, is obtained in the oxidation of iodine by stoichiometric amounts of S2O6F2 in trifluoromethanesulfonic acid, as a sparingly soluble precipitate. The compound is thermally stable up to +170° and its vibrational spectrum indicates the presence of both monodentate and bidentate bridging SO3CF3 groups. Reaction with the stoichiometric amount of iodine at +140° results in the formation of iodine(I) trifluoromethanesulfonate. Several routes to salts of the type MI[I(OSO2CF3)4], with MI = K, Rb, or Cs, are also described. Vibrational spectra for these and for IOSO2CF3 are reported.
