Figure 1
The molecular structure of (I) with the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level and ring H atoms have been omitted for clarity. Important hydrogen bonds are shown as broken lines [symmetry codes: (i) −x, ½ + y, ½ − z; (ii) 1 + x, y, z; (iii) 1 + x, ½ − y, ½ + z]. |
