The material structure described by NaPO3 crystallizes in the tetragonal I4_1/a space group. Na(1) is bonded in a 6-coordinate geometry to one O(3), two equivalent O(2), and three equivalent O(1) atoms. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing PO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Na(1) and one P(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Na(1) and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent P(1) atoms. is represented by the CIF card [CIF]
