Abstract
The crystal structure of a new terpenoid diol, trans-2,8-dihydroxy-l(7)-p-menthene, has been determined from three-dimensional X-ray data obtained near the temperature of liquid nitrogen. The structure was solved by application of the symbolic addition method for noncentrosymmetric crystals. It refined to an R index of 0.083. The methylenecyclohexane ring took on the ordinary chair conformation with the ring hydroxyl group axial and the 2-hydroxyisopropyl group equatorial. As indicated by the dihedral angles, 45.5 and 52.6°, the ring is flatter than that of cyclohexane. The molecules are held together in the crystal by a network of hydrogen bonds in which each hydroxyl participates in linkages with two other molecules. 1971, American Chemical Society.
