Abstract
In the title compound, C24H18N4O4, the plane of the phenyl ring is inclined to those of the toluene ring and the dinitro-substituted benzene ring by 66.96 (19) and 47.06 (18)°, respectively, while the planes of the two benzene rings are inclined to one another by 36.26 (19)°. There is an intramolecular N—H⋯O hydrogen bond between the NH group and the O atom of a nitro group, forming an S(6) ring motif. In the crystal, molecules are linked by C—H⋯O hydrogen bonds and C—H⋯π interactions, forming a three-dimensional network. There are also weak π–π interactions present involving the phenyl ring and the dinitro-substituted benzene ring [inter-centroid distance = 3.741 (2) Å].

Summary
C24H18N4O4, the plane of the phenyl ring is inclined to those of the toluene ring and the dinitrosubstituted benzene ring by 66.96 (19) and 47.06 (18) , respectively, while the planes of the two benzene rings are inclined to one another by 36.26 (19). There is an intramolecular N—H O hydrogen bond between the NH group and the O atom of a nitro group, forming an S(6) ring motif. Molecules are linked by C—H O hydrogen bonds and C—H interactions, forming a three-dimensional network. Absorption correction: multi-scan (SADABS; Bruker, 2005)
