-himachalene has been established. The atoms C10 and the gem-dimethyl groups C14 and C15 adopt two positions leading to two conformations for the seven-membered ring: boat-shaped (occupation factor 70%) and chair-shaped (30%). Modelling of these conformations agrees with the statistical distribution in the crystal.
