Abstract:
The title compound, C24H27N2Si+center dot Br-center dot 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) angstrom, and forms dihedral angles of 73.0 (3) and 39.6 (2)degrees, with the phenyl rings. In the crystal, molecules are linked by O-H center dot center dot center dot Br, C-H center dot center dot center dot Br and C-H center dot center dot center dot O hydrogen bonds. In addition, the structure features pi-pi stacking interactions, with a face-to-face separation of 3.644 (3) angstrom between parallel benzimidazole ring systems.
