The title compound, C11H16Cl4, was synthesized by the reaction of (1S)-β-pinene with triethyl­amine in the presence of ZnCl2. The cyclo­hexene ring assumes a half-boat conformation. The crystal packing is governed only by van der Waals inter­actions. The structure, which has been refined in P21, presents a striking P21/m pseudosymmetry.
