Title: Materials Data on Ti3Fe2Sb(PO4)6 by Materials Project

Abstract

Ti3Fe2Sb(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Ti+3.33+ sites. In the first Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra. There are three shorter (1.94 Å) and three longer (2.13 Å) Ti–O bond lengths. In the second Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.89 Å) and three longer (2.03 Å) Ti–O bond length. In the third Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.94 Å) and three longer (2.12 Å) Ti–O bond lengths. There are two inequivalent Fe+2.50+ sites. In the first Fe+2.50+ site, Fe+2.50+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one TiO6 octahedra, and a faceface with one SbO6 octahedra. There are three shorter (2.17 Å) and three longer (2.22 Å) Fe–O bond lengths. In the second Fe+2.50+ site, Fe+2.50+ is bondedmore » in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.23 Å) and three longer (2.28 Å) Fe–O bond lengths. Sb3+ is bonded to six O2- atoms to form distorted SbO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra. There are three shorter (2.15 Å) and three longer (2.35 Å) Sb–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one FeO6 octahedra, a cornercorner with one SbO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 20–51°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one FeO6 octahedra, a cornercorner with one SbO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 25–55°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ti+3.33+, one Fe+2.50+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti+3.33+, one Fe+2.50+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Fe+2.50+, one Sb3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ti+3.33+, one Fe+2.50+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom.« less
