Materials Data on MnNi(PO4)2 by Materials Project
Abstract
MnNi(PO4)2 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.19 Å) and three longer (2.23 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.90 Å) and three longer (2.00 Å) Mn–O bond length. In the third Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with six PO4 tetrahedra and faces with two NiO6 octahedra. There are three shorter (2.15 Å) and three longer (2.16 Å) Mn–O bond lengths. There are three inequivalent Ni4+ sites. In the first Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one MnO6 octahedra. There are three shorter (2.00 Å) and three longer (2.10 Å) Ni–O bond lengths. In the second Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with sixmore »

In the first Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one MnO6 octahedra. There are three shorter (2.00 Å) and three longer (2.10 Å) Ni–O bond lengths. In the second Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.96 Å) and three longer (2.05 Å) Ni–O bond lengths. In the third Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one MnO6 octahedra. There are three shorter (1.98 Å) and three longer (2.07 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 corners with two MnO6 octahedra and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 26–51°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two MnO6 octahedra and corners with three NiO6 octahedra. The corner-sharing octahedra tilt angles range from 30–49°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni4+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Ni4+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Ni4+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Mn2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Ni4+, and one P5+ atom.
