摘要：

The crystal structure of a-hafnium bis(monohydrogen orthophosphate)monohydrate, an inorganic ion-exchanger, was solved by the X-ray Rietveld technique utilizing synchrotron radiation (SR) as the X-ray source. This compound is monoclinic with space group P21/n and cell parameters a=9.0142(1), b=5.25665(5), c=15.4768(2) Å and β=101.636(1)°. Intensity data were collected by a capillary method with monochromatic X-rays of wavelength λ=1.49977(1) Å. The results were compared with those obtained by a conventional X-ray source and the advantages of SR in Rietveld analysis were verified. Despite the difference in the Li-ion exchange behavior between the α-hafnium phosphate and the α-zirconium phosphate, both phases were found to be isostructural with each other. © 1990, The Japan Society for Analytical Chemistry.
