Title: Materials Data on Na6Te(PO5)6 by Materials Project

Abstract

Na6Te(PO5)6 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Na sites. In the first Na site, Na is bonded to six O atoms to form distorted NaO6 pentagonal pyramids that share corners with four equivalent PO4 tetrahedra, edges with two equivalent NaO6 pentagonal pyramids, and faces with two equivalent NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.50–2.64 Å. In the second Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share corners with two equivalent TeO6 octahedra, corners with two equivalent PO4 tetrahedra, and faces with two equivalent NaO6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 38°. There are a spread of Na–O bond distances ranging from 2.28–2.59 Å. P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one NaO6 octahedra, corners with two equivalent NaO6 pentagonal pyramids, and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. Te is bonded to six equivalent O atoms to form distorted TeO6 octahedra that share corners with six equivalent NaO6more » octahedra. The corner-sharing octahedral tilt angles are 38°. All Te–O bond lengths are 1.92 Å. There are six inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent P atoms. In the second O site, O is bonded in an L-shaped geometry to two Na atoms. In the third O site, O is bonded in an L-shaped geometry to two Na atoms. In the fourth O site, O is bonded in a single-bond geometry to one P atom. In the fifth O site, O is bonded in a distorted rectangular see-saw-like geometry to three Na and one P atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Na and one Te atom.« less
