Figure 1
The molecular structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Numerical data refer to the internal torsion angles (°) of the individual rings (s.u. values vary between 0.1 and 0.3°). Intramolecular C—H⋯O short contacts are shown as dashed lines. |
