1,2,3,5-Tetrahydronaphtho[2,1-c]oxepine

Abstract

In the title compound, C14H14O, the seven-membered ring is in a pseudo-chair conformation. In the crystal, molecules are linked by weak C—H...O hydrogen bonds forming layers parallel to (010). In addition, there are weak π–π stacking interactions between inversion-related naphthalene ring systems, with a ring centroid–ring centroid distance of 3.518 (5) Å.
