Leitz, Dominik; Stierstorfer, Karin; Morgenstern, Yvonne; Zischka, Florian; Kornath, Andreas J. (2018): The Influence of the Counterions [AsF6](-) and [GeF6](2-) on the Structure of the [ClSO2NH3](+) Cation. In: Zeitschrift für Anorganische und Allgemeine Chemie, Vol. 644, No. 10: pp. 483-488

Chlorosulfonamide reacts in the superacidic solutions HF/GeF4 and HF/AsF5 under the formation of ([ClSO2NH3](+))(2)[GeF6](2-) and [ClSO2NH3](+)[AsF6](-), respectively. The chlorosulfonammonium salts were characterized by X-ray single crystal structure analysis as well as vibrational spectroscopy and discussed together with quantum chemical calculations. ([ClSO2NH3](+))(2)[GeF6](2-) crystallizes in the triclinic space group P1 with one formula unit in the unit cell. [ClSO2NH3](+)[AsF6](-) crystallizes in the monoclinic space group P2(1)/n with four formula units in the unit cell. Dependent on the counterion, [AsF6](-) or [GeF6](2-), considerable structural differences of the [ClSO2NH3](+) cation are observed. Furthermore, the hitherto unknown X-ray single crystal structure of chlorosulfonamide is determined in the course of this study. Chlorosulfonamide crystallizes in the orthorhombic space group Pmc2 with four formula units per unit cell.
