Abstract: | Preparation of CF3SClF+MF6? (M = As, Sb) and Crystal Structure of CF3SCl2+SbF6? CF3SClF+MF6? (M = As, Sb) is prepared by oxidative fluorination of CF3SCl with XeF+MF6?. The new salt is characterized by IR, Raman and NMR spectra in comparison with CF3SF2+MF6? and CF3SCl2+MF6?. In SO2 solution CF3SClF+SbF6? symmetrizises into CF3SF2+SbF6? and crystalline CF3SCl2+SbF6? with the monoclinic space group P21/c with a = 773.5(14) pm, b = 954.8(15) pm, c = 1242.0(18) pm, β = 100.24(8)°, Z = 4. |
