In the title compound, C28H24O4, the benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost antiparallel, and the benzene rings make a dihedral angle of 20.03 (7)°. The dihedral angles between the benzene rings and the naphthalene ring system are 68.42 (5) and 71.69 (5)°. In the crystal, adjacent molecules are linked via C—H
O hydrogen bonds, forming chains propagating along [100].

The asymmetric unit of the title compound, C23H18O3, contains two independent molecules (A and B). Each molecule has essentially the same conformation (r.m.s. deviation of fitted molecules = 0.173 Å) with the aromatic rings twisted in a near perpendicular manner. The dihedral angles between the two naphthalene ring systems are 79.07 (4) and 88.19 (4)° in the two independent molecules. In the crystal, the A molecules are connected by C—HO interactions, forming chains along the b-axis direction. Further C—HO interactions between the H atoms of the methoxy group and the O atoms of the carbonyl units link the A and B molecules, forming a three-dimensional network.
