    Description / Table of Contents: Preparation of (C6F5)2SF+MF6- (M = As, Sb) and Crystal Structure of (C6F5)2SF+SbF6-XeF+MF6- (M = As, Sb) reacts with (C6F5)2S in HF to form (C6F5)2SF+MF6-. The deeply violet sulfonium salts can be kept without decomposition up to 24 h at room temperature.The hexafluoroantimonate salt crystallizes in the monoclinic space group P21/n with a = 1056.4(7) pm, b = 1446.3(10) pm, c = 1102.9(8) pm, β = 91.29(6)° und Z = 4. The SF-bond distance with 158.4(3) pm is of unusual length. Cations and anions are connected via interionic fluorine contacts to an infinite chain, in which cations and anions form to ABAB sequence along the chain.
    Notes: XeF+MF6- (M = As, Sb) reagiert mit (C6F5)2S in HF zu (C6F5)2SF+MF6-/. Die beiden tiefvioletten Sulfoniumsalze sind bei Raumtemperatur bis zu 24 Stunden unzersetzt haltbar.Das Hexafluoroantimonat kristallisiert in der monoklinen Raumgruppe P21/n mit a = 1056,4(7) pm, b = 1446,3(10) pm, c = 1102,9(8) pm, β = 91,29(6)° und Z = 4. Der SF-Bindungsabstand ist mit 158,4(3) pm außergewöhnlich lang. Kationen und Anionen werden durch interionische Fluor-Kontakte zu einer unendlichen Kette verknüpft, in der Kationen und Anionen in einer ABAB-Folge angeordnet sind.
