Bottom Line: The ester O-C=O plane and the benzene ring are almost coplanar, making a dihedral angle of 3.81 (18)°.In the crystal structure, a centrosymmetric dimer is formed through C-H⋯O bonds connecting the 7-meth-oxy group and the carbonyl O atom of the ester group.The dimers are further linked by C-H⋯O hydrogen bonds between the methoxy-carbonyl group and the bridging carbonyl O atom.

ABSTRACT
In the title compound, C(21)H(18)O(5), the dihedral angle between the naphthalene ring system and the benzene ring is 86.65 (6)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 83.57 (7) and 20.21 (8)°, respectively, with the naphthalene ring system and the benzene ring. The ester O-C=O plane and the benzene ring are almost coplanar, making a dihedral angle of 3.81 (18)°. The two meth-oxy groups lie essentially in the naphthalene ring plane [C-O-C-C torsion angles = 2.1 (2) and -1.44 (19)°]. In the crystal structure, a centrosymmetric dimer is formed through C-H⋯O bonds connecting the 7-meth-oxy group and the carbonyl O atom of the ester group. The dimers are further linked by C-H⋯O hydrogen bonds between the methoxy-carbonyl group and the bridging carbonyl O atom.
