Materials Data on Ti3CrNi2(PO4)6 by Materials Project
Abstract
Ti3CrNi2(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one NiO6 octahedra. There is three shorter (1.91 Å) and three longer (2.06 Å) Ti–O bond length. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.91 Å) and three longer (2.05 Å) Ti–O bond length. In the third Ti4+ site, Ti4+ 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 (2.06 Å) Ti–O bond length. Cr2+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one NiO6 octahedra. There is three shorter (1.95 Å) and three longer (2.03 Å) Cr–O bond length. There are two inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form distorted NiO6 octahedra that sharemore »

Cr2+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one NiO6 octahedra. There is three shorter (1.95 Å) and three longer (2.03 Å) Cr–O bond length. There are two inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one TiO6 octahedra, and a faceface with one CrO6 octahedra. All Ni–O bond lengths are 2.16 Å. In the second Ni2+ site, Ni2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.17 Å) and three longer (2.18 Å) Ni–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 CrO6 octahedra, a cornercorner with one NiO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 26–49°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CrO6 octahedra, a cornercorner with one NiO6 octahedra, and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 26–50°. There are a spread of P–O bond distances ranging from 1.51–1.57 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Ni2+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Ni2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Cr2+, one Ni2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Ni2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom.},
