Figure 1
Part of the polymeric structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. Atoms labelled with the suffixes A, B and C are generated by the symmetry operations (−x, 2 − y, −z), (2 − x, 1 − y, −z) and (−x, 1 − y, 1 − z), respectively. |
