R. Minkwitz et al., ON THE REACTIONS OF MOLECULES (R(2)CS)(2) (R=CF3, CL) AND CL2CS WITH XEF(-) (M=AS, SB) AND CRYSTAL-STRUCTURE OF (CF3)(2)CSC(CF3)(2)SF+SBF6-()MF(6)(), Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 49(7), 1994, pp. 881-888
XeF(+)MF(6)(-) (M = As, Sb) reacts with ((CF3)(2)CS)(2) and Cl2CS to f
orm the corresponding monofluorinated sulfonium hexafluorometalates. T
he salts have been characterized by vibrational and F-19 NMR spectrosc
opic measurements. (CF3)(2)CSC(CF3)(2)SF+SbF6- crystallizes in the mon
oclinic space group C2/c with a = 14.791(10), b = 11.093(6), c = 10.35
6(6)Angstrom, beta = 119.83 degrees and Z = 4. With a value of 1.51(1)
Angstrom d(S-F) is comparable to the SF-bond distance in (CF3)(Cl)CSC
(CF3)(Cl)SF+AsF6-.
