Materials Data on KNa2(PO3)3 by Materials Project
Abstract
KNa2(PO3)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.74–3.48 Å. There are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.57 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.42–2.60 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent NaO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NaO6 octahedra and corners with two PO4 tetrahedra.

In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Na1+, and one P5+ atom.
