The asymmetric unit of the title compound, C(26)H(20)O(4), contains two independent conformers. The aromatic rings of the aroyl groups are twisted with respect to the naphthalene ring systems to form dihedral angles of 66.58 (6) and 66.45 (6)° in one conformer, and 75.00 (7) and 81.17 (6)° in the other conformer. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and by C-H⋯π inter-actions.
标题化合物C(26)H(20)O(4)的不对称单元包含两个独立的构象异构体。在一种构象异构体中，芳酰基的芳环相对于萘环体系发生扭曲，形成的二面角分别为66.58 (6)°和66.45 (6)°；在另一种构象异构体中，二面角分别为75.00 (7)°和81.17 (6)°。晶体堆积通过弱的分子间C-H⋯O氢键和C-H⋯π相互作用得以稳定。
