Rietveld plot for ReO2 from AlfaAesar (#62109, 99.9% pure) with an indication of the phases α-ReO2, β-ReO2 and ReO3. The inset shows the α-ReO2 (011) peak with the fitting result. High-resolution synchrotron X-ray powder diffraction at ambient pressure was performed with X-rays of wavelength 1.24000 (3) Å using a Ge(111) analyzer crystal. |
