Title: Materials Data on Li2MnFe3O8 by Materials Project

Abstract

Li2MnFe3O8 is Spinel-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent MnO6 octahedra and corners with nine equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 55–63°. All Li–O bond lengths are 1.98 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with three equivalent MnO6 octahedra, corners with three equivalent FeO6 octahedra, and edges with three equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 62–63°. There is one shorter (1.79 Å) and three longer (1.99 Å) Li–O bond length. Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent FeO6 octahedra, corners with six LiO4 tetrahedra, and edges with three equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There is three shorter (1.97 Å) and three longer (2.01 Å) Mn–O bond length. Fe+2.33+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent MnO6 octahedra, cornersmore » with four LiO4 tetrahedra, an edgeedge with one MnO6 octahedra, edges with four equivalent FeO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Fe–O bond distances ranging from 1.95–2.05 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one Mn7+, and two equivalent Fe+2.33+ atoms. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, one Mn7+, and two equivalent Fe+2.33+ atoms. In the third O2- site, O2- is bonded to one Li1+ and three equivalent Fe+2.33+ atoms to form distorted corner-sharing OLiFe3 trigonal pyramids. In the fourth O2- site, O2- is bonded to one Li1+ and three equivalent Fe+2.33+ atoms to form distorted corner-sharing OLiFe3 tetrahedra.« less
