The title compound was synthesized by treating (1S,3R,8S,9R,10S)-2,2-di­chloro-3,7,7,10-tetra­methyl-9,10-ep­oxy­tri­cyclo­[6.4.0.01,3]dodecane with a concentrated solution of hydro­bromic acid. It is built up from three fused rings: a cyclo­heptane ring, a cyclo­hexyl ring bearing alkene and hy­droxy substituents, and a cyclo­propane ring bearing two chlorine atoms.

The asymmetric unit of title compound contains two independent mol­ecules which are built from three fused rings: a heptane ring, a cyclo­hexyl ring bearing a ketone and an alcohol group, and a three-membered cyclo­propane ring bearing two Cl atoms. In the crystal, the mol­ecules are linked by O—H⋯O and C—H⋯O hydrogen bonds, forming chains propagating along [100].

The title compound, C16H24Cl2O, is built up from two fused six- and seven-membered rings which bear a di­chloro­cyclo­propane group and an ep­oxy group, respectively. In the mol­ecule, the six-membered ring adopts an envelope configuration with the C atom linking the ep­oxy ring at the flap, while the seven-membered ring adopts a boat–sofa conformation.
