2,7-Dimeth-oxy-1-(2-naphtho-yl)naph-thalene.
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.
