Figure 1
The molecular structure of (I), with the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are showwn as spheres of arbitrary radius. Hydrogen bonds are indicated by double-dashed lines. [Symmetry codes: (i) −x, 1 − y, 1 − z; (ii) −x, 2 − y, 1 − z.] |
