In the title compound, C(19)H(16)O(3), the dihedral angle between the naphthalene ring system and the phenyl ring is 68.32 (5)°. The bridging carbonyl C-C(=O)-C plane makes a dihedral angle of 54.32 (5)° with the naphthalene ring system and 21.45 (6)° with the phenyl ring. An inter-molecular C-H⋯O hydrogen bond exists between the H atom of one meth-oxy group and the O atom of the second meth-oxy group in an adjacent mol-ecule. The crystal packing is additionally stabilized by a weak C-H⋯O inter-molecular inter-action between an H atom of the naphthalene ring and the O atom of the carbonyl group.
在标题化合物C(19)H(16)O(3)中，萘环体系与苯环之间的二面角为68.32 (5)°。桥连羰基C-C(=O)-C平面与萘环体系的二面角为54.32 (5)°，与苯环的二面角为21.45 (6)°。一个甲氧基的H原子与相邻分子中第二个甲氧基的O原子之间存在分子间C-H⋯O氢键。萘环的一个H原子与羰基的O原子之间的弱C-H⋯O分子间相互作用进一步稳定了晶体堆积。
