Figure 1
The structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines indicate hydrogen bonds. Aromatic H atoms have been omitted for clarity. [Symmetry codes: (i) −x + 2, −y, z; (ii) x, y, z + 1; (iii) x, y, z − 1.] |
