In the crystal of the title compound, C19H14N4O4, the asymmetric unit consists of two discrete mol­ecules. The C=N bonds in both mol­ecules show an E conformation. The dihedral angles between the C atoms of the 2,4-dinitrobenzene rings and the C=N—N planes are 13.52 (9) and 13.82 (9)° for the two mol­ecules. In the crystal, C—H...O hydrogen bonds, mainly between the phenyl ring and the nitro group along the b axis.
