Abstract
The mol-ecular structure of the title salt, C11H12N3O3+·Br-, reveals near co-planarity between the the imidazole and 4-nitro-benzene moieties with a dihedral angle of 8.99 (14)° between their planes. A prominent feature in the mol-ecular packing is the bromide anion acting as a double acceptor for O-H⋯Br and C-H⋯Br hydrogen-bonds, leading to a linear chain propagating along [110]. The crystal studied was refined as an inversion twin, with the minor component = 0.081 (8).
