The title compound, C 22 H 20 N 2 + ÁBr À ÁH 2 O, was synthesized from 1-benzylbenzimidazole and 2-bromoethylbenzene in dimethylformamide. The dihedral angle between the two phenyl rings is 70.6 (1) . These phenyl rings make dihedral angles of 52.99 (9) and 83.03 (8) with the benzimidazole ring syst
ÁBr À ÁH 2 O, was determined at 150 K. It is a supramolecular adduct of imidazolium bromide and water molecules. Helical chains of (H 2 OÁBr À ) exist in the structure along the [001] direction. Each chain forms extensive hydrogen bonds with the imidazolium cations.
