Figure 1
The structure of compound (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. For the sake of clarity, only one orientation is shown for the disordered aryl ring (see Comment). Hydrogen bonds are represented by dashed lines. [Symmetry codes: (i) x, 1 − y, − + z; (ii) x, −y, + z; (iii) x, 1 − y, + z; (iv) x, −y, − + z.] |
