Abstract:
In the title compound, C14H21N2Si+center dot Br-center dot H2O, the benzimidazole ring system is almost planar [maximum deviation = 0.021 (2) angstrom]. In the crystal, O-H center dot center dot center dot Br and C-H center dot center dot center dot O hydrogen bonds link the ions via the O atoms of the water molecules. In addition, there are pi-pi stacking interactions between the centroids of the benzene and imidazole rings of the benzimidazole ring system [centroid-centroid distances = 3.521 (3) and 3.575 (2) angstrom].
