In the title compound, C36H24O6, the benzoyl groups at the 1- and 8-positions of the naphthalene system are in an anti orientation. Both carbonyl groups form intramolecular O—HO hydrogen bonds with hydroxy groups affording six-membered rings. The benzene rings of the benzoyl groups make dihedral angles of 59.26 (13) and 59.09 (13)° with the naphthalene ring system. Zigzag C—HO chains and ladder C—HO chains between the phenoxybenzoyl groups along the ab diagonals form an undulating checkered sheet. The molecules are further connected into a three-dimensional network by C—Hπ interactions.

In the title compound, C31H20O5, the phenyl rings of the benzoyloxy and benzoyl groups are twisted away from the naphthalene ring system by 64.27 (6), 73.62 (5) and 80.41 (6)°. In the crystal, C—HO hydrogen bonds and C—Hπ interactions link the molecules, forming tubular chains parallel to the b axis. The chains are further connected into a three-dimensional network by C—Hπ interactions and π–π stacking contacts [centroid–centroid distances = 3.622 (10)–3.866 (12) Å].

The entire title molecule, C42H36O6, is completed by the application of a twofold axis. The 4-phenoxybenzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost antiparallel. The dihedral angle between the best planes of the benzene rings of the benzoyl moieties and the naphthalene ring system is 70.52 (5)° and that between the best planes of the benzene rings of the phenoxy groups and the naphthalene ring system is 27.80 (6)°. In the crystal, molecules are linked into a three-dimensional architecture by C—HO and C—Hπ interactions.
