Abstract
The title compound, C13H9N3O5, prepared as a solid derivative of 3-nitroanaline via reaction with 4-nitrobenzoyl chloride, crystallizes in a chiral space group. The molecule is non-planar with a dihedral angle of 26.1 (1)° between the two benzene rings. Both nitro groups are twisted slightly out of the plane of their corresponding benzene rings, making dihedral angles of 10.7 (4) and 13.5 (4)°. The molecules are stacked along the a axis with benzene ring centroid–centroid distances of 3.8878 (6) Å. In the crystal, intermolecular benzene C—H⋯O interactions involving one nitro group and the carbonyl group link the molecules, forming chains along [001]. An additional set of aromatic C—H⋯O interactions with the second nitro group form chains along [101], connecting adjacent chains to create layers perpendicular to the b axis.
