Materials Data on VFe2Ni3(PO4)6 by Materials Project
Abstract
VFe2Ni3(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra. There is three shorter (1.81 Å) and three longer (2.02 Å) V–O bond length. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one VO6 octahedra, and a faceface with one NiO6 octahedra. There are three shorter (2.05 Å) and three longer (2.16 Å) Fe–O bond lengths. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra and faces with two NiO6 octahedra. There are three shorter (2.06 Å) and three longer (2.08 Å) Fe–O bond lengths. There are three inequivalent Ni+2.33+ sites. In the first Ni+2.33+ site, Ni+2.33+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra. There are three shorter (1.99 Å) and three longer (2.17 Å) Ni–Omore »

There are three shorter (2.06 Å) and three longer (2.08 Å) Fe–O bond lengths. There are three inequivalent Ni+2.33+ sites. In the first Ni+2.33+ site, Ni+2.33+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra. There are three shorter (1.99 Å) and three longer (2.17 Å) Ni–O bond lengths. In the second Ni+2.33+ site, Ni+2.33+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one FeO6 octahedra.

There are three shorter (1.96 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 VO6 octahedra, corners with two FeO6 octahedra, and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–59°. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one VO6 octahedra, corners with two FeO6 octahedra, and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 32–52°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni+2.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Fe3+, one Ni+2.33+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Fe3+, one Ni+2.33+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni+2.33+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one V5+, one Fe3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Fe3+, one Ni+2.33+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni+2.33+ and one P5+ atom.},
