Abstract: 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-H...Br, C-H...Br and C-H...O hydrogen bonds. In addition, the structure features [pi]-[pi] stacking interactions, with a face-to-face separation of 3.644 (3) Å between parallel benzimidazole ring systems.
