Figure 6
Packing diagrams of the high- and low-temperature phases, viewed down the b axis. The twofold screw axes and the inversion centres are shown by black symbols. The space group in the high-temperature phase is P21/c, while the space group in the low-temperature phase is taken to be P21/n in order to show the structural relationship between the two phases. All H atoms have been omitted for clarity.
