✦ Synopsis

In the title compound, C 27 H 25 N 5 O 8 , the p-vanillin (4-hydroxy-3-methoxybenzaldehyde) group makes dihedral angles of 5.80 (8), 66.34 (6) and 68.13 (7) with the pyrazolone ring, the terminal dinitrobenzene ring and the terminal phenyl ring, respectively. The crystal packing is stabilized by intermolecular C-HÁ Á ÁO C and C-HÁ Á ÁO N hydrogen bonds that form centrosymmetric dimers.
