Materials Data on Ti3Mn2Sb(PO4)6 by Materials Project
Ti3Mn2Sb(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 and a faceface with one MnO6 octahedra. There are three shorter (1.95 Å) and three longer (2.13 Å) Ti–O bond lengths. 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 (1.88 Å) and three longer (2.03 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 are three shorter (1.95 Å) and three longer (2.10 Å) Ti–O bond lengths. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 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 (2.22 Å) and three longer (2.25 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are three shorter (2.29 Å) and three longer (2.34 Å) Mn–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 MnO6 octahedra. There are three shorter (2.14 Å) and three longer (2.36 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 MnO6 octahedra, a cornercorner with one SbO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 21–49°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one MnO6 octahedra, a cornercorner with one SbO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 24–55°. 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+3.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ti+3.67+, one Mn2+, 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+3.67+, one Mn2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Mn2+, one Sb3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ti+3.67+, one Mn2+, 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.
