Figure 4
(a) Geometric relation between the 7200 Å3 cell of cs521 (black) and the 1800 Å3 cell of cs511 (blue). The fault planes (green dotted lines) lie parallel to {110} in the 7200 Å3 cell, equivalent to {100} in the 1800 Å3 cell. (b) Fault planes overlaid on a schematic of the cs521 structure and depicting {110} fault planes with 00½ displacement across the faults. Each `armed rectangle' is an exaggerated representation of the point symmetry 2 of the molecule. (c) Average structure overlaid on the 7200 Å3 cell and assuming 50% disorder caused by the 00½ fault. (d) Average structure overlaid on the 1800 Å3 cell (blue) and the 7200 Å3 cell (black). There is 50% occupancy at each site. The symmetry elements correspond to the space group P42 for the 1800 Å3 cell. |
