Figure 1
Top: the molecular structure of (I,I-A). Displacement ellipsoids are shown at the 50% probability level. Only the crystallographically unique atoms are labeled. The labelings for (I,I-B) and (I,I-C) are the same and the displacement ellipsoids are similar. Bottom: the molecular structure of (I,Cl). Only the major component of the disorder [fraction equal to 0.586 (2)] is shown in full, with displacement ellipsoids at the 50% probability level. The minor component is shown only in outline. The ellipsoids in the minor component are constrained to be identical to those of the overlapping atoms in the major component. The two components lie on a pseudosymmetry center in the space group Pc. |
