A comprehensive spectroscopic characterization of all known crystalline AlF3 phases (α-, β-, η-, κ-, θ-AlF3) is presented for the first time in this study. Beside their X-ray diffraction powder patterns, which were already published in the literature, 27Al and 19F MAS NMR, FT IR and XPS spectroscopic techniques were applied for all phases in a consistent manner. For all phases prepared the utilization of 27Al satellite transition (SATRAS) NMR allowed to determine the quadrupolar parameters of the aluminium sites including their distributions.In addition, η-AlF3 was isolated with high phase purity and characterized following a new preparation path different from those known so far in the literature.
27Al and 19F MAS NMR, FT IR and XPS-characterization of various crystalline AlF3 phases have been comprehensively performed.Figure optionsDownload as PowerPoint slide
