4-Anilino-3-nitro-N-phenylbenzamide

In the title compound, C19H15N3O3, the anilino and benzamide rings make dihedral angles of 10.66 (16) and 50.39 (16)degrees, respectively, with the nitro-substituted benzene ring. The nitro group is slightly twisted by 11.49 (17)degrees with respect to the attached benzene ring. There is an intramolecular N-H center dot center dot center dot O hydrogen bond forming an S(6) ring. In the crystal, weak intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into a chain parallel to the b axis. Futhermore, weak slipped pi-pi interactions [centroid-centroid distance = 3.819 (2) angstrom, interplanar distance = 3.567 angstrom and offset angle [how is the offset angle defined?] = 21 degrees] between the anilino ring and its symmetry-related counterpart may help to stabilize the packing.
