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
