[2,7-Dihy­droxy-8-(4-phen­oxy­benzo­yl)naphthalen-1-yl](4-phen­oxy­phen­yl)methanone

In the title compound, C(36)H(24)O(6), the benzoyl groups at the 1- and 8-positions of the naphthalene system are in an anti orientation. Both carbonyl groups form intra­molecular O—H⋯O 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—H⋯O chains and ladder C—H⋯O 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⋯π interactions.
