 Title    Collidinium-und Imidazolium-Salze Fluor-haltiger Anionen  
 Abstract    Die Kristall­ struktur von [CollH]2 [AsF6][As2 Fu ] (Coli = 2,4,6-Trimethylpyridin) Collidinium and Imidazolium Salts of Fluorine-Containing Anions. The Crystal Structure of [CollH]2[AsF6][As2Fl l ] (Coll = 2,4,6-Trimethylpyridine) From s-Collidine (1, Coll) and aqueous HF compounds of the composition Coll • n HF (n = 1 -2) are formed which are transformed to [CollH]+ [HF2]~ (2) by sublimation. [CollH]2[AsF6][As2F] J (3) is obtained from 1 and the superacid system HF/AsF5. 2 reacts with 2,3-dihydro-l,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (4, Im) to give the imidazo­ lium salt [ImH]+ [HF2]~ (5). Hydrogen bonds in the crystal structure of [CollH]2[AsF6][As2Fn ] (3) are discussed.
