title: [2,7-Dibut-oxy-8-(4-fluoro-benzo-yl)naphthalen-1-yl](4-fluoro-phen-yl)methanone.
abstract: In the title compound, C32H30F2O4, the benzene rings of the benzoyl groups make dihedral angles of 74.55 (6) and 74.39 (7)° with the naphthalene ring system. In the crystal, intra- and inter-molecular C-H⋯π inter-actions are observed between the but-oxy group and the aromatic rings. There are also C-H⋯F hydrogen bonds present that link the mol-ecules into chains propagating along [010].
