| Popis: | C18H22=3 Mr=286.4, orthorhombic, P212121, a=7.014(2), b=12.176(4), c=17.648(4)A, V=1507.2 A3, Z=4, Dx=1.26 Mg m-3m (Mo Ka)=0.71069 A, µ=0.079 mm-1m F(000)=616, T ca 130 K, R=0.109 for all 2506 unique reflections within -1sinO=0.70 A-1; the absolute configuration was not determined. The relative stereochemistry at C(10) is established. The unsaturated ring is essentially planar; the two central rings are in the chair conformation and the five-membered ring adopts the envelope conformation. |
