Abstract: The asymmetric unit of the title compound, C7H11N3O5S, contains two independent molecules with virtually identical conformations. The imidazole rings of both molecules are essentially planar (r.m.s. deviations = 0.0019 and 0.0038 Å), with a dihedral angle 9.25 (19)° between them. The nitro groups are oriented at 4.5 (2) and 6.44 (13)° with respect to the imidazole rings. In the crystal, molecules are linked to form a three-dimensional framework by C-HO and C-HN hydrogen bonds.
