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

Abstract

In the title compound, C36H24O6, the benzoyl groups at the 1- and 8-positions of the naphthalene system are in anantiorientation. 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 theabdiagonals form an undulating checkered sheet. The molecules are further connected into a three-dimensional network by C—H...π interactions.
