摘要：

Alternative and, in some cases, improved syntheses of the salts MX3(As/Sb)F6 (M = S, Se) and SCl3(SbCl6/AlCl4) are described. In addition, the synthesis of SeCl3SbF6 is reported. The compounds were characterized by FT-Raman spectroscopy and the X-ray crystal structures of SeCl3AsF6 (also 77Se NMR) and a new phase of SBr3SbF6 were determined. Crystals of SeCl3AsF6 and SBr3SbF6 are monoclinic, space group P21/c with [values for SBr3SbF6 in brackets] a = 7.678(1) [8.137(1)] angstrom, b = 9.380(3) [9.583(2)] angstrom, c = 11.920(3) [12.447(2)] angstrom, β = 98.19(2)° [97.36(1)]°, V = 849.72(3) [962.6(3)] angstrom3, z = 4, Dx = 2.925 [3.502] Mg m-3, R = 0.0525 [0.055], and Rw = 0.0554 [0.060] for 1151 [1472] observed reflections.
