title: (3,6-Dimeth-oxy-naphthalen-2-yl)(naphthalen-2-yl)methanone.
abstract: In the title compound, C(23)H(18)O(3), the dihedral angle between the two naphthalene ring systems is 78.02 (3)°. The bridging carbonyl C-C(=O)-C plane makes a dihedral angle of 70.56 (5)° with the naphthalene ring system in the 2,7-dimeth-oxy-naphthalene moiety and a dihedral angle of 11.53 (5)° with the naphthalene ring system in the naphthoyl group. In the crystal, adjacent mol-ecules are linked via C-H⋯π inter-actions, forming chains along [010].
