Title: Materials Data on TiCr2Ni3(PO4)6 by Materials Project

Abstract

TiCr2Ni3(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one CrO6 octahedra. There is three shorter (1.86 Å) and three longer (2.09 Å) Ti–O bond length. There are two inequivalent Cr4+ sites. In the first Cr4+ site, Cr4+ is bonded to six O2- atoms to form distorted CrO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one TiO6 octahedra, and a faceface with one NiO6 octahedra. There are three shorter (2.07 Å) and three longer (2.09 Å) Cr–O bond lengths. In the second Cr4+ site, Cr4+ is bonded to six O2- atoms to form distorted CrO6 octahedra that share corners with six PO4 tetrahedra and faces with two NiO6 octahedra. There are three shorter (2.05 Å) and three longer (2.07 Å) Cr–O bond lengths. There are three 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 and a faceface with one CrO6 octahedra. There are three shorter (1.96 Å) and three longer (2.11more » Å) Ni–O bond lengths. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one CrO6 octahedra. There are three shorter (2.00 Å) and three longer (2.12 Å) Ni–O bond lengths. In the third Ni2+ site, Ni2+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one CrO6 octahedra. There are three shorter (1.99 Å) and three longer (2.08 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 TiO6 octahedra, corners with two CrO6 octahedra, and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 28–54°. There are a spread of P–O bond distances ranging from 1.50–1.60 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one TiO6 octahedra, corners with two CrO6 octahedra, and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 25–57°. There are a spread of P–O bond distances ranging from 1.52–1.56 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Cr4+, one Ni2+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Cr4+, one Ni2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Cr4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Cr4+, one Ni2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni2+ and one P5+ atom.« less
