Materials Data on LiFe3SiPO8 by Materials Project
Abstract
LiFe3SiPO8 is Ilmenite-derived structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four equivalent FeO6 octahedra, corners with two equivalent PO4 tetrahedra, edges with two equivalent LiO6 octahedra, edges with two equivalent FeO6 octahedra, and edges with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 60–69°. There are a spread of Li–O bond distances ranging from 2.14–2.27 Å. There are three inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with eight FeO6 octahedra, a cornercorner with one PO4 tetrahedra, corners with three equivalent SiO4 tetrahedra, edges with two equivalent LiO6 octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–66°. There are a spread of Fe–O bond distances ranging from 2.08–2.30 Å. In the second Fe2+ site, Fe2+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with four equivalent FeO6 octahedra, a cornercorner with one SiO4 tetrahedra, corners with three equivalent PO4 tetrahedra, edges with twomore »
