The title compound, C24H27N2Si+·Br−·H2O, was synthesized from 1-(dimethylphenylsilylmethyl)-1H-benzimidazole and (2-bromoethyl)benzene in dimethylformamide. The benzimidazole ring system is nearly planar, with a maximum deviation of 0.015 (5) Å, and forms dihedral angles of 73.0 (3) and 39.6 (2)°, with the phenyl rings. In the crystal, molecules are linked by O—HBr, C—HBr and C—HO hydrogen bonds. In addition, the structure features π–π stacking interactions, with a face-to-face separation of 3.644 (3) Å between parallel benzimidazole ring systems.
