4-[(E)-3-Methoxy-5-nitro-4-(4-nitrobenzyloxy)benzylideneamino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
In the title compound, C26H23N5O7, the central benzene ring makes dihedral angles of 35.08 (6), 48.75 (7) and 69.55 (8)° with the pyrazolone ring, the nitrobenzene ring and the terminal phenyl ring, respectively. An intramolecular C—H⋯O interaction generates an S(6) ring. The packing is stabilized by weak nonclassical intermolecular C—H⋯O=C hydrogen bonds that link adjacent molecules into chains
