Abstract

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][As2F11] (3) is obtained from 1 and the superacid system HF/AsF5. 2 reacts with 2,3-dihydro-1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (4, Im) to give the imidazolium salt [ImH](+)[HF2](-) (5). Hydrogen bonds in the crystal structure of [CollH](2)[ASF(6)] [As2F11] (3) are discussed.
