1-Benzyl-3-[(trimethylsilyl)methyl]benzimidazolium chloride monohydrate

Abstract

The title compound, C18H23N2Si +·Cl-·H2O, was synthesized from 1-[(trimethylsilyl)methyl]benzimidazole and benzyl chloride in dimethyl-formamide. The benzimidazole ring system is approximately planar, with a maximum deviation of 0.022 (2) Å, and makes an angle of 74.80 (12)° with the phenyl ring. The crystal packing is stabilized by O-H⋯Cl, C-H⋯Cl, C-H⋯O and C-H⋯π inter-actions between symmetry-related molecules together with π-π stacking inter-actions between the imidazolium and benzene rings [centroid-centroid distance = 3.5690 (15) Å] and between the benzene rings [centroid-centroid distance = 3.7223 (14) Å].
