Figure 1
The independent molecular components of (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. Atoms marked `a' or `b' are at the symmetry positions (−x, y, z) and (−x + 1, y, z), respectively. The water molecule lies across the twofold rotation axis along (, y, ). |
