چکیده
The title compound, C(26)H(18)N(4)O(5), can be regarded as an extended ether with two terminal nitro groups. The two aryl rings bonded to the central O atom form a dihedral angle of 75.72 (6)°, and the terminal nitro groups are slightly twisted [by 6.4 (2) and 3.3 (3)°] from the benzene rings to which they are attached. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.794 (3) Å].
