R. Conanec et al., CRYSTAL-STRUCTURE DETERMINATION OF THE NITRIDOPHOSPHATE NA3ALP3O9N, European journal of solid state and inorganic chemistry, 31(1), 1994, pp. 13-24
The crystal structure of the nitridophosphate Na3AlP3O9N has been dete
rmined from single crystal data. The unit cell is cubic [space group P
2(1)3 (Z = 4)] with a = 9.274(1) angstrom. Nitrogen is bonded to three
tetrahedral phosphorus atoms, thus forming N(PO3)3 groups around octa
hedral aluminum atoms. The structure of Na3AlP3O9N can be compared to
that of the langbeinite K2Mg2(SO4)3.
