(Top) Powder diffraction patterns for 2P (left) and 4P (right) measured at the pressure point and on decompression (dec.). (Bottom) Powder diffraction Le Bail refinements, with the crystal planes seen on decompression images marked. The insets show projections of the crystal structures used to visualize an (h00) plane family.
