The asymmetric unit of the compound, C19H15FO3, contains two independent molecules. Each molecule has essentially the same feature of non-coplanarly accumulated aromatic rings whereby the aroyl group at the 1-position of the naphthalene ring system is twisted almost perpendicularly to the ring system [dihedral angles of 86.52 (8) and 89.

The title compound, C28H22N2O8, possesses crystallographically imposed twofold symmetry, with the two central carbon atoms of the naphthalene unit lying on the rotation axis. The two benzoyl groups in the mol-ecule are twisted away from the attached naphthalene unit with a C-C-C=O torsion angle of 49.05 (15)° between the naphthalene unit and the carbonyl group.
