[3-Benzoyl-2,4-bis­(3-nitro­phen­yl)cyclo­but­yl](phen­yl)methanone

The asymmetric unit of the title compound, C₃₀H₂₂N₂O₆, comprises a half-mol­ecule of the cyclo­butane derivative. The least-squares planes defined by the respective C atoms of the aromatic substituents inter­sect at angles of 76.81 (7) and 89.22 (8)° with the least-squares plane defined by the C atoms of the cyclo­butane ring. In the crystal, C—H...O contacts connect the mol­ecules into a three-dimensional network. The shortest centroid–centroid distance between the two different aromatic rings is 3.9601 (8) Å.
