Abstract
An x-ray structural investigation (λ Mo Kα2ϑ/θ scanning for 2ϑ<50°, MLS in the anisotropic approximation) has been performed of cadinene dihydrochloride (I) (1213 reflections, R=0.053) and muurolene dihydrochloride (II) 1643 reflections, R=0.087). The crystals of (I) belong to the rhombic system with a=6.053(2), b=14.622(5), c=17.926(7) A, Z=4, sp. gr. P212121, mp 117°C. The crystals of (II) belong to the monoclinic system, with a=9.842(4), b=11.627(6), c=13.677(9) Å, β=95.10(4)°, Z=4, sp. gr. P21, mp 86°C. The six-membered rings of the molecules (I) and (II) have the chair conformation with equatorial alkyl groups. The chlorine atoms have the axial arrangement. The molecule of (I) has the 3α,9α-dichlorocadinane structure, and that of (II) the 3β,9α-dichlormuurolane structure. The increased mean length of the C-Cl bonds of 1.844 Å in the molecule of (I) and 1.879 Å in the molecule of (II) must be mentioned.
