چکیده
In the title compound, C(26)H(23)N(5)O(7), the central benzene ring makes dihedral angles of 35.08 (6), 48.75 (7) and 69.55 (8)° with the pyrazolone ring, the nitro-benzene ring and the terminal phenyl ring, respectively. An intra-molecular C-H⋯O inter-action generates an S(6) ring. The packing is stabilized by weak nonclassical inter-molecular C-H⋯O=C hydrogen bonds that link adjacent mol-ecules into chains.
