Abstract
In the title compound, C11H12BrN2 +·Br−, the imidazole and phenyl rings are nearly perpendicular, making a dihedral angle of 87.71 (7)°. The crystal structure is stabilized by non-classical intermolecular C—H⋯Br hydrogen bonds and inversion-related molecules are linked through π–π interactions between the imidazole ring systems [centroid–centroid distance = 3.472 (6) Å].
