Synchrotron powder study of Na(3)V(PO(3))(3)N

Polycrystalline tris­odium vanadium(III) nitridotriphosphate, Na(3)V(PO(3))(3)N, was prepared by thermal nitridation of a mixture of NaPO(3) and V(2)O(5). The title compound is isotypic with Na(3)Al(PO(3))(3)N. In the crystal, the P-atom and the three O-atom sites are on general positions, whereas the Na-, V- and N-atom sites are located on threefold rotation axes. The P atom is coordinated by three O atoms and one N atom in form of a slightly distorted tetra­hedron. Three PO(3)N tetra­hedra build up a nitridotriphosphate group, (PO(3))(3)N, by sharing a common N atom. The V atom is coordinated by six O atoms in form of a slightly distorted octa­hedron. The Na(+) ions occupy three crystallographically distinct sites. One Na(+) ion is situated in an irregular polyhedral coordination environment composed of six O atoms and one N atom, while the other two Na(+) cations are surrounded by six and nine O atoms, respectively.
