The title compound, C(16)H(24)Cl(2)O, was synthesized from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzocyclo-heptene), which was isolated from essential oil of the Atlas cedar (Cedrus atlantica). The two fused rings exhibit different conformations: the six-membered ring has a screw-boat conformation, while the seven-membered ring displays a boat conformation. The dihedral angle between the two rings is 56.56 (18)°. In the crystal, mol-ecules aggregate into supra-molecular chains along the c axis mediated by O-H⋯O hydrogen bonds.
标题化合物C(16)H(24)Cl(2)O由β-喜马拉雅烯(3,5,5,9-四甲基-2,4a,5,6,7,8-六氢-1H-苯并环庚烯)合成,β-喜马拉雅烯是从阿特拉斯雪松(Cedrus atlantica)的精油中分离得到的。两个稠合环呈现出不同的构象:六元环具有扭船式构象,而七元环呈现船式构象。两个环之间的二面角为56.56 (18)°。在晶体中,分子通过O-H⋯O氢键沿c轴聚集形成超分子链。
