title: 4-Nitro-N-(3-nitro-phen-yl)benzamide.
abstract: The title compound, C(13)H(9)N(3)O(5), prepared as a solid derivative of 3-nitro-analine via reaction with 4-nitro-benzoyl chloride, crystallizes in a chiral space group. The mol-ecule 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 mol-ecules are stacked along the a axis with benzene ring centroid-centroid distances of 3.8878 (6) Å. In the crystal, inter-molecular benzene C-H⋯O inter-actions involving one nitro group and the carbonyl group link the mol-ecules, forming chains along [001]. An additional set of aromatic C-H⋯O inter-actions with the second nitro group form chains along [101], connecting adjacent chains to create layers perpendicular to the b axis.
