Materials Data on Li2AlFeO4 by Materials Project
Li2FeAlO4 is beta beryllia-derived structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.97–2.28 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent FeO4 tetrahedra and corners with four equivalent AlO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.01–2.04 Å. Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra and corners with four equivalent AlO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.89–1.92 Å. Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra and corners with four equivalent FeO4 tetrahedra. All Al–O bond lengths are 1.79 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Fe3+, and one Al3+ atom. In the second O2- site, O2- is bonded to two Li1+, one Fe3+, and one Al3+ atom to form corner-sharing OLi2AlFe tetrahedra. In the third O2- site, O2- is bonded to two Li1+, one Fe3+, and one Al3+ atom to form corner-sharing OLi2AlFe tetrahedra. In the fourth O2- site, O2- is bonded to two Li1+, one Fe3+, and one Al3+ atom to form corner-sharing OLi2AlFe tetrahedra.
