In the mol-ecule of the title compound, C32H24O5, the benzoyl group and the 4-phenoxy substituted benzoyl group at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel. The two benzene rings make a dihedral angle of 21.18 (10)°, and are inclined to the naphthalene ring system by 86.53 (9) and 82.95 (8)°, respectively. In the crystal, C-H⋯O inter-actions are observed involving aromatic and meth-oxy H atoms with ketonic carbonyl O atoms, as well as C-H⋯π inter-actions between aromatic H atoms and the π-systems of naphthalene and benzene rings. These interactions form a three-dimensional architecture and afford a waved alignment of the naphthalene ring systems along the c axis.
在标题化合物C₃₂H₂₄O₅的分子中，萘环体系1位和8位的苯甲酰基和4-苯氧基取代苯甲酰基几乎呈反平行排列。两个苯环形成的二面角为21.18 (10)°，且分别与萘环体系呈86.53 (9)°和82.95 (8)°的倾斜度。在晶体中，观察到C-H⋯O相互作用，涉及芳香族和甲氧基H原子与酮羰基O原子，以及芳香族H原子与萘环和苯环的π体系之间的C-H⋯π相互作用。这些相互作用形成三维结构，并使萘环体系沿c轴呈波浪状排列。
