4-Anilino-3-nitro-N-phenyl­benzamide

In the title compound, C(19)H(15)N(3)O(3), the anilino and benzamide rings make dihedral angles of 10.66 (16) and 50.39 (16)°, respectively, with the nitro-substituted benzene ring. The nitro group is slightly twisted by 11.49 (17)° with respect to the attached benzene ring. There is an intra­molecular N—H⋯O hydrogen bond forming an S(6) ring. In the crystal, weak inter­molecular N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a chain parallel to the b axis. Futhermore, weak slipped π–π inter­actions [centroid–centroid distance = 3.819 (2) Å, inter­planar distance = 3.567 Å and offset angle [how is the offset angle defined?] = 21°] between the anilino ring and its symmetry-related counterpart may help to stabilize the packing.
