The title racemic triquinane, C14H14Cl2O2, is composed of four five-membered rings, one of which is a tetrahydrofuran ring to which an allyl group on one side and a hydroxyl group on the other side are attached. The core of the triquinane unit has a cis–syn–cis configuration. In the crystal, the molecules are linked by pairwise O—H...O hydrogen bonds, generating inversion dimers featuring R22(8) loops.
