Crystal structure of 7,8,9,10-tetra­hydro­benzo( b]naphtho­ )2,1-d furan

In the title compound, C16H14O, the cyclohexene ring has a half-chair conformation. The mean plane, calculated through all non-H atoms of the molecule, except for the central CH2 atoms of the cyclohexene ring, which deviate by 0.340 (3) and 0.369 (3) A˚ from this mean plane, has an r.m.s. deviation of 0.012 A˚ . In the crystal, there are C—H contacts present, resulting in the formation of zigzag chains propagating along the [010] direction.
