Materials Data on Ti3Mn(PO4)6 by Materials Project

Abstract

Ti3Mn(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Ti+3.67+ sites. In the first Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.92 Å) and three longer (1.96 Å) Ti–O bond length. In the second Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.93 Å) and three longer (1.97 Å) Ti–O bond length. In the third Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.93 Å) and three longer (1.95 Å) Ti–O bond length. Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.89 Å) and three longer (1.93 Å) Mn–O bond length. 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 MnO6 octahedra and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–29°. There is one shorter (1.53 Å) and three longer (1.54 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one MnO6 octahedra and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–33°. There is one shorter (1.53 Å) and three longer (1.54 Å) P–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn7+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn7+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom.
