MgAPO-20 is the magnesium aluminophosphate equivalent of the zeolite sodalite with magnesium, aluminum, and phosphorus in the tetrahedral framework sites. The authors have measured {sup 27}Al and {sup 31}P magic-angle-spinning (MAS) NMR spectra of this material and demonstrate that (i) all spectral signals can be assigned; (ii) the framework composition can be calculated from the spectra; (iii) the magnesium in the framework is strictly ordered; (iv) the precise nature of this ordering can be determined.
