In the mol-ecule of the title compound, C28H22F2O4, the benzoyl groups are aligned almost anti-parallel and the fluorobenzene rings form a dihedral angle of 14.12 (7)°. The dihedral angles between the 2,7-dieth-oxy-naphthalene ring system and the benzene rings are 70.00 (4) and 67.28 (4)°. In the crystal, mol-ecules 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 π-π inter-actions [centroid-centroid distances of 3.6115 (10) Å] into a three-dimensional structure.
在标题化合物C₂₈H₂₂F₂O₄的分子中，苯甲酰基几乎呈反平行排列，氟苯环形成的二面角为14.12（7）°。2,7 - 二乙氧基萘环系与苯环之间的二面角分别为70.00（4）°和67.28（4）°。在晶体中，分子通过C—H⋯O和C—H⋯F氢键相连，形成平行于ab平面的层。这些层通过π - π相互作用[质心 - 质心距离为3.6115（10）Å]进一步连接成三维结构。
