Abstract: In the molecule of the title compound, C28H22F2O4, the benzoyl groups are aligned almost antiparallel and the fluorobenzene rings form a dihedral angle of 14.12 (7)°. The dihedral angles between the 2,7-diethoxynaphthalene ring system and the benzene rings are 70.00 (4) and 67.28 (4)°. In the crystal, molecules are linked by C-H...O and C-H...F hydrogen bonds, forming layers parallel to the ab plane. The layers are further connected by [pi]-[pi] interactions [centroid-centroid distances of 3.6115 (10) Å] into a three-dimensional structure.
