2-Methoxynaphthalene, C11H10O, crystallizes as a nearly planar molecule, with the methoxy group adopting a syn-periplanar conformation with respect to the C atom. A search of the Cambridge Structural Database [Allen, F. & Kennard, O. (1993). Chem. Des. Autom. News, 8, 31-37] reveals that this conformation is characteristic of the -methoxynaphthalene moiety, because, for each of the four exceptions found, a valid explanation can be given as to why they display a different conformation.
