Title: Materials Data on LiAlFeO4 by Materials Project

Abstract

LiFeAlO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li is bonded in a 3-coordinate geometry to three O atoms. There are one shorter (1.96 Å) and two longer (2.10 Å) Li–O bond lengths. Fe is bonded to six O atoms to form FeO6 octahedra that share corners with three equivalent AlO6 octahedra, edges with two equivalent FeO6 octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 27–53°. There are a spread of Fe–O bond distances ranging from 1.91–2.07 Å. Al is bonded to six O atoms to form AlO6 octahedra that share corners with three equivalent FeO6 octahedra, edges with two equivalent FeO6 octahedra, and edges with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 27–53°. There are a spread of Al–O bond distances ranging from 1.85–1.97 Å. There are four inequivalent O sites. In the first O site, O is bonded to one Fe and three equivalent Al atoms to form OAl3Fe trigonal pyramids that share a cornercorner with one OLi2AlFe2 trigonal bipyramid, corners with two equivalent OAl3Fe trigonal pyramids, edges with two equivalent OLi2AlFe2 trigonal bipyramids, and edges with two equivalent OAl3Fe trigonal pyramids. Inmore » the second O site, O is bonded in a 3-coordinate geometry to one Li and two equivalent Fe atoms. In the third O site, O is bonded in a trigonal planar geometry to one Fe and two equivalent Al atoms. In the fourth O site, O is bonded to two equivalent Li, two equivalent Fe, and one Al atom to form distorted OLi2AlFe2 trigonal bipyramids that share a cornercorner with one OAl3Fe trigonal pyramid, edges with two equivalent OLi2AlFe2 trigonal bipyramids, and edges with two equivalent OAl3Fe trigonal pyramids.« less
