Figure 1
The structure of (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 40% probability level and H atoms are shown as small spheres of arbitrary radii. The dashed lines indicate O—H⋯O interactions. [Symmetry codes: (i) −x, y, − z; (ii) x, 1 − y, + z; (iii) −x, 1 − y, 1 − z.] |
