 Title    Polysulfonylamine, XXXI [1] Kristallstruktur von (1-Trichlormethylthio- 4-dimethylaminopyridinium)dimesylamid bei -9 5 °C Polysulfonylamines, XXXI [1] Crystal Structure o f 1-Trichloromethylthio- 4-dimethylaminopyridinium Dimesylamide at -9 5 °C  
 Abstract    The crystal structure o f the title com pound was determined at -9 5 °C. It crystallizes in space group P 1 with a = 577.5(3), b = 820.2(3), c = 1916.6(8) pm, a = 83.34(2), ß = 82.83(2), y = 83.61(2)° and Z = 2. The final R value was 0.034 for 3019 unique observed reflections. The presence o f aggregates o f four ions (two cations and two an­ ions) in the solid state is observed, with short cat-ion-anion contacts Sn — 0 (290 pm) and Cl --O (298 pm). The bond lengths o f the 4-dimethyl-aminopyridinium moiety o f the cation suggest a semiquinoid resonance form with a double bond to the nitrogen o f the dim ethylam ino group and two localized double bonds in the ring. The ring, the dimethylamino group (except H atom s) and the Sn atom are coplanar. The S " -N bond length is 170.3 pm, the N -S " -C angle 99.6°. The S ° -C bond is approximately perpendicular to the ring plane.
