Notes:
The apparent contradiction between NMR and X-ray results concerning the Si, A1 distribution in zeolite A is quantitatively analysed. It is concluded that the Fm{\bar 3}c structure model, based on X-ray refinements, is compatible with the NMR data if a cautious chemical-shift assignment is applied. The appropriate use of crystallographic approximations and their symmetry is discussed.
