title: (E)-1,5-Dimethyl-4-[3-(4-nitro-benz-yloxy)benzyl-ideneamino]-2-phenyl-1H-pyrazol-3(2H)-one.
abstract: In the title compound, C(25)H(22)N(4)O(4), the central benzene ring, makes dihedral angles of 74.35 (6), 17.01 (8) and 62.19 (7)°, respectively, with the nitro-benzyl ring, the pyrazolone ring and the terminal phenyl ring. Inter-molecular C-H⋯O hydrogen bonds help to consolidate the crystal packing.
