Figure 1
The structure of (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 30% probability level. Carbon-bound H atoms have been omitted and water H atoms are shown as small spheres of arbitrary radii. The dashed line indicates the intramolecular hydrogen bond. [Symmetry codes: (i) −x, 2 − y, 1 − z; (ii) −x, 1 − y, 1 − z.] |
