Crystal structures of high-pressure phases in the alumina-water system: II. Powder X-ray diffraction study of a new dense aluminum deuteroxide, delta-Al(OD)(3)

摘要

In this study we report the solution of the structure of delta-Al(OD)(3). The crystal structure was determined using powder X-ray diffraction and direct methods, while the positions of deuterium atoms were estimated by difference-Fourier methods and MEM/Rietveld analysis. In the A-site deficient hydroxy-perovskite-type structure of delta-Al(OD)(3), we find two types of one-dimensional H-bonding network.
