3-(2-Hy­droxy­eth­yl)-1-(4-nitro­phen­yl)-1H-benzo[d]imidazol-3-ium bromide

Abstract

In the crystal of the title salt, the bromide ions act as double acceptors for hydrogen bonds from a hydroxyl group (O—H⋯Br) and a fused imidazolium moiety (C—H⋯Br). Additionally, C—H⋯O hydrogen bonds between the phenyl group and hydroxyl oxygen atom create a two-dimensional supra­molecular network extending diagonally in the crystallographic bc plane.

The cation of the title salt, C₁₅H₁₄N₃O₃⁺·Br⁻, has a dihedral angle of 24.26 (6)° between its fused imidazole and 4-nitro­phenyl rings and the N—C—C—O torsion angle associated with the hy­droxy­ethyl substituent is 60.15 (17)°. In the crystal, the bromide ions act as double acceptors for hydrogen bonds from a hydroxyl group (O—H⋯Br) and a fused imidazolium moiety (C—H⋯Br). Additionally, C—H⋯O hydrogen bonds between the phenyl group and hydroxyl oxygen atom create a two-dimensional supra­molecular network extending diagonally in the crystallographic bc plane.
