Abstract:
A range of aluminate sodalites of general formula M8(AlO2)12.X2, where M and X are a divalent cation and anion, respectively, has been synthesised. The structures of these materials, which contain a single aluminum environment, have been refined from powder X-ray or neutron diffraction data and the compounds further characterised using 27Al magic-angle spinning nuclear magnetic resonance (MAS NMR). Correlations between (i) the Al-O-Al bond angles and the 27Al chemical shift and (ii) the quadrupolar coupling constant and the distorted AlO4 tetrahedral geometry have been determined.
