Title: Materials Data on Na5TiP2O9F by Materials Project

Abstract

Na5TiP2O9F crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are six inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to five O2- and one F1- atom to form distorted NaO5F octahedra that share a cornercorner with one TiO5F octahedra, corners with two NaO6 octahedra, corners with four PO4 tetrahedra, a cornercorner with one NaO4F trigonal bipyramid, an edgeedge with one NaO4F trigonal bipyramid, a faceface with one NaO5F octahedra, and a faceface with one TiO5F octahedra. The corner-sharing octahedra tilt angles range from 45–79°. There are a spread of Na–O bond distances ranging from 2.27–2.57 Å. The Na–F bond length is 2.47 Å. In the second Na1+ site, Na1+ is bonded to four O2- and one F1- atom to form distorted NaO4F trigonal bipyramids that share a cornercorner with one TiO5F octahedra, corners with two NaO5F octahedra, corners with four PO4 tetrahedra, and edges with three NaO5F octahedra. The corner-sharing octahedra tilt angles range from 8–84°. There are a spread of Na–O bond distances ranging from 2.32–2.37 Å. The Na–F bond length is 2.41 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to five O2- and one F1-more » atom. There are a spread of Na–O bond distances ranging from 2.33–2.75 Å.
