title: [2,7-Dihy-droxy-8-(4-phen-oxy-benzo-yl)naphthalen-1-yl](4-phen-oxy-phen-yl)methanone.
abstract: 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 intra-molecular O-H⋯O hydrogen bonds with hy-droxy 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.
