The title compound possesses crystallographically imposed twofold symmetry with two C atoms lying on the rotation axis and has a non-coplanarly accumulated aromatic-rings structure. In the crystal, C—HO=C hydrogen bonds between the benzene rings and the carbonyl groups and C—HO=N hydrogen bonds between the benzene rings and the nitro groups are observed; these C—HO hydrogen bonds link the molecules, forming a three-dimensional structure.

The asymmetric unit of the compound contains two independent conformers. Each conformer is stacked along the a axis to form columns through van der Waals interactions only.
