title: [3-Benzoyl-2,4-bis-(3-nitro-phen-yl)cyclo-but-yl](phen-yl)methanone.
abstract: The asymmetric unit of the title compound, C30H22N2O6, comprises a half-mol-ecule of the cyclo-butane derivative. The least-squares planes defined by the respective C atoms of the aromatic substituents inter-sect at angles of 76.81 (7) and 89.22 (8)° with the least-squares plane defined by the C atoms of the cyclo-butane ring. In the crystal, C-H⋯O contacts connect the mol-ecules into a three-dimensional network. The shortest centroid-centroid distance between the two different aromatic rings is 3.9601 (8) Å.
