(a) The cell parameters of samples A and B from synchrotron single-crystal X-ray diffraction (SXRD) and conventional powder X-ray diffraction (PXRD). (b) The (204) reflection plotted as a function of temperature collected with a conventional X-ray source (sample B). (c) A high-resolution synchrotron PXRD pattern showing asymmetries at 550 K (sample B). |
