Materials Data on LiFe2(PO4)3 by Materials Project
Abstract
LiFe2(PO4)3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Li is bonded to six O atoms to form LiO6 octahedra that share corners with six PO4 tetrahedra and edges with two FeO6 octahedra. There are a spread of Li–O bond distances ranging from 2.09–2.28 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra, an edgeedge with one LiO6 octahedra, and an edgeedge with one FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.94–2.18 Å. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six equivalent PO4 tetrahedra and edges with two equivalent FeO6 octahedra. There are two shorter (1.94 Å) and four longer (2.13 Å) Fe–O bond lengths. In the third Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six equivalent PO4 tetrahedra and edges with two equivalent LiO6 octahedra. There is two shorter (1.95 Å) and four longer (2.04 Å) Fe–O bond length. There are three inequivalent P sites. In themore »

There is two shorter (1.95 Å) and four longer (2.04 Å) Fe–O bond length. There are three inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three equivalent LiO6 octahedra and corners with three equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 42–57°. There is one shorter (1.54 Å) and three longer (1.55 Å) P–O bond length. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with six FeO6 octahedra. The corner-sharing octahedra tilt angles range from 44–54°. There is two shorter (1.53 Å) and two longer (1.58 Å) P–O bond length. In the third P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three equivalent LiO6 octahedra and corners with three equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 42–57°. There is one shorter (1.54 Å) and three longer (1.55 Å) P–O bond length. There are nine inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Li and one P atom. In the second O site, O is bonded in a bent 120 degrees geometry to one Li and one P atom. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one Fe and one P atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the fifth O site, O is bonded in a distorted trigonal planar geometry to one Li, one Fe, and one P atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the seventh O site, O is bonded in a distorted trigonal planar geometry to one Li, one Fe, and one P atom. In the eighth O site, O is bonded in a distorted bent 120 degrees geometry to one Fe and one P atom. In the ninth O site, O is bonded in a distorted trigonal planar geometry to two Fe and one P atom.},
