Abstract: 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-H interactions.
