1,3-Bis(3-Phenylpropyl)Benzimidazolium Bromide Monohydrate

Abstract

In the title compound, C<inf>25</inf>H<inf>27</inf>N<inf>2</inf> +·Br-·H<inf>2</inf>O, the benzimidazole unit is essentially planar, with a maximum deviation of 0.020 (6) Å. The benzimidazole unit makes dihedral angles of 83.6 (3) and 81.0 (3)° with the two terminal phenyl rings. The dihedral angle between the phenyl rings is 58.5 (4)°. In the crystal structure, there are C - H...O hydrogen bonds, a C - H...π inter-action between a phenyl H atom and the phenyl ring of a neighbouring mol-ecule, and a π-π inter-action [3.512 (3) Å] between the centroids of the five-membered ring and the benzene ring of the benzimidazole unit of an adjacent mol-ecule.
