Figure 4
The superposition of the defined positions for molecules 1 and 2 and the position of molecule 3 after applying the centre of inversion showing the close similarity with the disordered standard model depicted in Fig. 1. Displacement ellipsoids are drawn at the 50% probability level. H atoms are omitted for clarity. A prime (′) denotes atoms transformed through the operation (1-x, 1-y, 1-z). |
