NaCa(PO2)3 crystallizes in the cubic P2_13 space group. Na(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form NaO6 octahedra that share edges with three equivalent Ca(1)O6 octahedra. Ca(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CaO6 octahedra that share edges with three equivalent Na(1)O6 octahedra. P(1) is bonded in a bent 120 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Na(1), one Ca(1), and one P(1) atom. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one Na(1), one Ca(1), and one P(1) atom.
