title: Crystal structure of 7,8,9,10-tetra-hydro-benzo[b]naphtho-[2,1-d]furan.
abstract: In the title compound, C16H14O, the cyclo-hexene ring has a half-chair conformation. The mean plane, calculated through all non-H atoms of the mol-ecule, except for the central CH2 atoms of the cyclo-hexene ring, which deviate by 0.340 (3) and -0.369 (3) Å from this mean plane, has an r.m.s. deviation of 0.012 Å. In the crystal, there are C-H⋯π contacts present, resulting in the formation of zigzag chains propagating along the [010] direction.
