In the title mol-ecule, C(23)H(18)O(3), the dihedral angle between the two naphthalene ring systems is 80.44 (4)°. The mean plane of the bridging carbonyl C-C(=O)-C group makes a torsion angle of -68.55 (17)° with the naphthalene system of the 2,7-dimeth-oxy-naphthalene unit and a torsion angle of -9.01 (19)° with the naphthalene ring system of the naphthoyl group. In the crystal, a weak C-H⋯O hydrogen bond occurs between the carbonyl O atom and an H atom of the naphthalene ring in the 2,7-dimeth-oxy-naphthalene unit of a symmetry-related mol-ecule.
在标题分子C(23)H(18)O(3)中，两个萘环系统之间的二面角为80.44 (4)°。桥连羰基C-C(=O)-C基团的平均平面与2,7-二甲氧基萘单元的萘环系统形成的扭转角为-68.55 (17)°，与萘甲酰基的萘环系统形成的扭转角为-9.01 (19)°。在晶体中，一个对称相关分子的2,7-二甲氧基萘单元中的羰基O原子与萘环的一个H原子之间存在弱C-H⋯O氢键。
