title: 1-Isopropyl-4-nitro-6-meth-oxy-1H-benzimidazole.
abstract: There are two independent mol-ecules in the asymmetric unit of the title compound, C(11)H(13)N(3)O(3). The inter-planar angles for the two rings of the benzimidazole ring system is 2.21 (12)° in one mol-ecule and 0.72 (12)° in the other. The nitro group is twisted in the same direction relative to the least-squares plane through its attached benzene ring in both mol-ecules, with inter-planar angles of 15.22 (9) and 18.02 (8)°. In the crystal structure, mol-ecules are stacked along the a axis through π-π inter-actions (centroid-centroid distance 4.1954 Å). C-H⋯O hydrogen bonds are also present.
