N-(2,4-Dinitrophenyl)-N′-[nitro(phenyl)methylene]hydrazine

The title compound, C13H9N5O6, contains three nitro groups. It is prepared by the reaction of benzaldehyde 2,4-dinitrophenylhydrazone with nitric oxide at ambient temperature. The imine group is nearly coplanar with the (2,4-dinitrophenyl)hydrazine unit. The second benzene ring and the third nitro group are twisted away from this plane, with dihedral angles of 48.5 (3) and 15.2 (3)°, respectively. Weak intramolecular N—H...O interactions are observed
