Figure 6
Polyhedron plots of the four molecules contained in the unit cells at 230 K and below, viewed down the c axis. The M atom is shown in green, M′ in blue and P in purple; C atoms have been omitted for clarity. The plot for (III) at 293 K was prepared by using one component of the disordered O1 and O3 atoms. (a) (III) at 293 K; (b) (II) at 293 K; (c) (III) at 230 K; (d) (I) at 100 K; (e) (III) at 100 K. |
