title: 2-(4-Methyl-sulfanylphen-yl)-1H-benzimidazol-3-ium bromide.
abstract: In the cation of the title compound, C(14)H(13)N(2)S(+)·Br(-), the essentially planar benzimidazole system (r.m.s. deviation = 0.0082 Å) is substituted with a 4-methyl-sulfanylphenyl ring. The dihedral angle between the benzimidazole system and the 4-methyl-sulfanylphenyl ring is 2.133 (2)°. The crystal structure is characterized by strong and highly directional inter-molecular N-H⋯Br hydrogen bonds involving the bromide ion. Moreover, C-H⋯S inter-actions result in chains of mol-ecules along the c axis. The supra-molecular assembly is further stabilized by π-π stacking inter-actions between the benzimidazole system and 4-methyl-sulfanylphenyl rings [centroid-centroid distance = 3.477 (4) Å].
