N,N′-Bis[(E)-4-nitrobenzylidene]-4,4′-oxydianiline

The title compound, C26H18N4O5, 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 intermolecular C—H...O hydrogen bonds and π–π interactions [centroid–centroid distances = 3.794 (3) Å].
