Materials Data on Li2Mn3FeO8 by Materials Project
Abstract
Li2Mn3FeO8 is Spinel-derived structured and crystallizes in the orthorhombic Cmc2_1 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 FeO6 octahedra and corners with nine MnO6 octahedra. The corner-sharing octahedra tilt angles range from 56–61°. There is one shorter (1.97 Å) and three longer (1.98 Å) Li–O bond length. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with three MnO6 octahedra, corners with three equivalent FeO6 octahedra, and edges with three MnO6 octahedra. The corner-sharing octahedra tilt angles range from 61–63°. There is one shorter (1.79 Å) and three longer (1.93 Å) Li–O bond length. There are two inequivalent Mn+3.67+ sites. In the first Mn+3.67+ site, Mn+3.67+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with three equivalent LiO4 tetrahedra, a cornercorner with one LiO4 trigonal pyramid, an edgeedge with one FeO6 octahedra, edges with four MnO6 octahedra, and an edgeedge with one LiO4 trigonal pyramid.

In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two Mn+3.67+, and one Fe3+ atom. In the third O2- site, O2- is bonded to one Li1+, two equivalent Mn+3.67+, and one Fe3+ atom to form distorted OLiMn2Fe tetrahedra that share corners with four OLiMn3 tetrahedra and edges with two equivalent OLiMn2Fe tetrahedra. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+ and three Mn+3.67+ atoms. In the fifth O2- site, O2- is bonded to one Li1+ and three Mn+3.67+ atoms to form corner-sharing OLiMn3 tetrahedra.
