Figure 5
The molecular structure of (III), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Intramolecular hydrogen bonds are shown as dashed lines. The asymmetric unit consists of one half-molecule, and unlabeled atoms are related to labeled atoms by the symmetry operator (1 − x, 1 − y, −z). |
