Title: Materials Data on Li2Mn2Cr3O12 by Materials Project

Abstract

Li2Cr3Mn2O12 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with four CrO4 tetrahedra and edges with two equivalent MnO6 octahedra. There are a spread of Li–O bond distances ranging from 1.99–2.02 Å. There are two inequivalent Cr6+ sites. In the first Cr6+ site, Cr6+ is bonded to four O2- atoms to form CrO4 tetrahedra that share corners with four equivalent MnO6 octahedra and corners with two equivalent LiO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 21–40°. There is two shorter (1.65 Å) and two longer (1.69 Å) Cr–O bond length. In the second Cr6+ site, Cr6+ is bonded to four O2- atoms to form CrO4 tetrahedra that share corners with four equivalent MnO6 octahedra and corners with three equivalent LiO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 17–47°. There is one shorter (1.64 Å) and three longer (1.68 Å) Cr–O bond length. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six CrO4 tetrahedra and edges with two equivalent LiO4 trigonal pyramids. There are a spread of Mn–O bond distances rangingmore » from 2.10–2.21 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr6+, and one Mn2+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr6+, and one Mn2+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr6+, and one Mn2+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr6+, and one Mn2+ atom. In the fifth O2- site, O2- is bonded in a distorted linear geometry to one Cr6+ and one Mn2+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr6+ and one Mn2+ atom.« less
