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.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
