Figure 4
The molecular structure of (II), showing the atom-numbering scheme. Displacement ellipsoids are shown at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. The dashed line indicates the intramolecular hydrogen bond. [Symmetry codes: (v) 2 − x, −y, 1 − z; (vi) 3 − x, −y, 1 − z.] |
