Figure 6
The final Pawley refinement plot of phase II at 4.8 kbar 273 K, showing observed (o), calculated (line) and difference (lower) profiles. Vertical bar markers indicate calculated Bragg peak positions. The equivalent d-spacing range corresponds to 1.45–5.20 Å. The calculated powder pattern based on the single-crystal X-ray structure (Shallard-Brown et al., 2005) and using unit-cell and peak-width parameters from the Pawley refinement is shown in the inset. |
