چکیده
In the title salt, C(13)H(19)N(2) (+)·BF(4) (-), an ionic liquid, the butyl and ethyl substituents bonded to the N atoms of the imidazole ring [r.m.s. deviation = 0.019 (1) Å] adopt equatorial positions. The crystal structure exhibits slipped π-π inter-actions between the imidazole and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.529 (2) Å]. In the tetra-fluoro-borate anion, the B and F atoms are disordered over two sets of sites with site-occupancy factors of 0.813 (7) and 0.187 (7).

The asymmetric unit of the title compound, C(8)H(6)F(3)N(2) (+)·BF(4) (-)·C(8)H(5)F(3)N(2)·H(2)O, consists of two 2-trifluoro-methyl-benzimidazole mol-ecules, each of which is protonated on a 50% basis, one tetra-fluoro-borate anion and a water mol-ecule. The two 2-trifluoromethylbenzimidazole mol-ecules thus exist as half-neutral half-cation entities. They are linked by N-H⋯N hydrogen bonds in...
