The title compound, C(11)H(16)Cl(4), was synthesized by the reaction of (1S)-β-pinene with triethyl-amine in the presence of ZnCl(2). The cyclo-hexene ring assumes a half-boat conformation. The crystal packing is governed only by van der Waals inter-actions. The structure, which has been refined in P2(1), presents a striking P2(1)/m pseudosymmetry.
