Materials Data on Sb(PO3)4 by Materials Project

Abstract

Sb(PO3)4 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sb–O bond distances ranging from 2.07–2.22 Å. There are two inequivalent P+4.75+ sites. In the first P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra 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 1.46–1.64 Å. In the second P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SbO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–49°. There are a spread of P–O bond distances ranging from 1.52–1.58 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.75+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one P+4.75+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two P+4.75+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb5+ and one P+4.75+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb5+ and one P+4.75+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two P+4.75+ atoms.
