In the title mol-ecule, C(22)H(16)N(2)O(10), the dihedral angles between the benzene rings of the 4-nitro-phenyl groups and the central benzene ring are 32.7 (1) and 34.7 (1)°, while the dihedral angle between the two benzene rings of the 4-nitro-phenyl groups is 3.6 (2)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers.
