dc.description.abstract | The crystal and molecular structure of the title
compound, C16H20Os, has been determined by singlecrystal
X-ray diffraction. The compound crystallizes in
the monoclinic space group P2t/c with two molecules in a cell of dimensions a = 9.199 (1), b = 12.423 (1),
c = 8.047 (1) A, and fl = 114.87 (1) °. The structure
was solved by direct methods (MULTAN). Full-matrix
least-squares refinement gave a final agreement index of
R = 0.054 for 1166 observed reflections. The sixmembered
ring adopts the chair conformation around a symmetry centre. The conformation of the fivemembered
rings is nearer to a twist than to an envelope,
the approximate twofold axis passing through the C(4)
atom. The endocyclic C-O bonds are asymmetric and
the C=C distance is longer than expected for a double
bond. Crystal packing is due to van der Waals interactions
only. | es |
