Article abstract of DOI:10.1021/ic50189a002

Dithionitronium hexachloroantimonate(V), (S₂N)(SbCl₆), has been prepared by the reactions of S₇NH, S₇NBCl₂, and 1,4-S₆N₂H₂ with SbCl₅ in liquid SO₂. The structure of the compound has been determined by single-crystal X-ray diffraction. The orthorhombic crystal, space group I222, has cell dimensions a = 9.299 (3) ?, b = 7.976 (3) ?, and c = 7.070 (2) ? and has two formula units in the unit cell. Intensities were measured using Mo Ka radiation and a Syntex P2₁ diffractometer. The crystal structure was determined by standard methods and refined to R₁ - 0.0377, R₂ = 0.0375. The crystal is composed of linear S₂N⁺ cations (N-S = 1.464 (3) ?) and approximately octahedral SbCl₆^- anions (Sb-Cl = 2.351 (3), 2.363 (2) ?). Infrared and Raman spectra of the solid compound are reported.
