Figure 8
Anomalous difference Fourier map for PPAT computed to 2.2 Å resolution. The map is projected down the [111] axis. The origin is located in the centre of the map and the location of the threefold symmetry axis is displayed in blue. Contours are at intervals of 0.1 e− Å−3. The map was computed from the data merged in point group 1. It can be seen that the threefold symmetry is broken. |
