Abstract
In the title compound, C25H27N2 +·Br−·H2O, 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 interaction between a phenyl H atom and the phenyl ring of a neighbouring molecule, and a π–π interaction [3.512 (3) Å] between the centroids of the five-membered ring and the benzene ring of the benzimidazole unit of an adjacent molecule.
