N-(2,4-Dinitrophenyl)-N′-(1-p-tolylethylidene)hydrazine

In the title molecule, C15H14N4O4, the dihedral angle between the two benzene rings is 2.21 (7)°. An intramolecular N—H...O hydrogen bond generates an S(6) ring motif. The mean planes of the ortho- and para-nitro groups make dihedral angles of 2.17 (17) and 2.05 (16)°, respectively, with the benzene ring to which they are attached. In the crystal structure, weak intermolecular C—H...O hydrogen bonds generate R22(7), R22(13) and R21(10) ring motifs, linking symmetry-related molecules into extended chains along the b axis. In addition, there are intermolecular C...C [3.332 (2)–3.343 (2) Å] contacts which are shorter than the sum of the van der Waals radii. The crystal structure is further stabilized by intermolecular C—H...π and π–π stacking interactions [centroid–centroid distance = 3.8090 (9) Å]
