Abstract
In the title molecule, C23H18O3, 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-dimethoxynaphthalene 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-dimethoxynaphthalene unit of a symmetry-related molecule.

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-dimethoxynaphthalene unit of a symmetry-related molecule
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
Summary
Symmetry code: (i) x þ 32; y 12; z þ 12. C23H18O3, 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-dimethoxynaphthalene unit and a torsion angle of. 9.01 (19) with the naphthalene ring system of the naphthoyl group. 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-dimethoxynaphthalene unit of a symmetry-related molecule.
