چکیده
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.
