	abstract = {The crystal structure of alpha -eucryptite, LiAlSiO4, is reinvestigated by combining Si-29 NMR spectroscopy and single-crystal X-ray diffraction. The silicon coordination in alpha -eucryptite of three different samples (two of natural, one of synthetic origin) is shown to be identical on a local scale by means of Si-29 MAS NMR spectroscopy. This method also suggests a well ordered arrangement of Si and Al within the crystal structure of alpha -eucryptite and the presence of two symmetrically non-equivalent sites for silicon. The refinement of the structure of a natural crystal using single-crystal X-ray diffraction confirms these observations and demonstrates the presence of long-range Al-Si order and the acentric space group R3.},
