摘要

In the title hydrated symetrically substituted 1,3-bis­(4-methyl­benz­yl)benzimidazolium salt, C23H23N2+·Br−·H2O, the dihedral angles between the benzimidazole ring system (r.m.s. deviation = 0.003 Å) and the pendant benzene rings are 73.18 (16) and 77.52 (16)°. Both benzene rings lie to the same side of the benzimidazole ring system, giving the cation an overall U-shape. In the crystal, the cation is linked to the water mol­ecule by a short C—H⋯O hydrogen bond and the water mol­ecule forms O—H⋯Br hydrogen bonds. Together, these inter­actions lead to [010] chains. The packing is consolidated by C—H⋯Br hydrogen bonds and aromatic π–π stacking inter­actions [centroid–centroid distances = 3.5401 (17) and 3.8815 (18) Å], generating a three-dimensional network.
