Figure 1
The structure of (I), showing the atom-labeling scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines indicate hydrogen bonds. [Symmetry codes: (i) x, −y + 1, −z; (ii) −x + 1, −y + 1, −z; (iii) −x + 1, y, z; (v) −x, y, z.] |
