Figure 3
The mol­ecular structure of (III)[link], with 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°). The intra­molecular C—H⋯O short contact is shown as a dashed line.
