4-Nitro-N-(3-nitro­phen­yl)benzamide

The title compound, C(13)H(9)N(3)O(5), 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.
