Title: Materials Data on LiFe4(PO4)4 by Materials Project

Abstract

LiFe4(PO4)4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four FeO6 octahedra, corners with two PO4 tetrahedra, edges with two FeO6 octahedra, and edges with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–68°. There are a spread of Li–O bond distances ranging from 2.06–2.30 Å. There are four inequivalent Fe+2.75+ sites. In the first Fe+2.75+ site, Fe+2.75+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent FeO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–68°. There are a spread of Fe–O bond distances ranging from 1.91–2.16 Å. In the second Fe+2.75+ site, Fe+2.75+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with four equivalent FeO6 octahedra, corners with four PO4 tetrahedra, an edgeedge with one LiO6 octahedra, and an edgeedge with one PO4 tetrahedra.
