Figure 1
The independent molecular components in (I), showing the atom-labelling scheme and the hydrogen bonds within the selected asymmetric unit (dashed lines). Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry codes: (i) 1 − x, 1 − y, 1 − z; (ii) 1 − x, −y, −z.] |
