Title: Materials Data on Li2Mn3O7 by Materials Project

Abstract

Li2Mn3O7 is beta indium sulfide-derived structured and crystallizes in the triclinic P-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 two equivalent LiO6 octahedra and corners with nine MnO6 octahedra. The corner-sharing octahedra tilt angles range from 52–67°. There are a spread of Li–O bond distances ranging from 1.96–2.14 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four MnO6 octahedra, corners with two equivalent LiO4 tetrahedra, an edgeedge with one LiO6 octahedra, and edges with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 9–15°. There are a spread of Li–O bond distances ranging from 2.03–2.41 Å. There are three inequivalent Mn4+ sites. In the first Mn4+ site, Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent LiO4 tetrahedra, an edgeedge with one LiO6 octahedra, and edges with five MnO6 octahedra. The corner-sharing octahedra tilt angles range from 9–10°. There are a spread of Mn–O bond distancesmore » ranging from 1.86–2.01 Å. In the second Mn4+ site, Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with three equivalent LiO4 tetrahedra, edges with two equivalent LiO6 octahedra, and edges with five MnO6 octahedra. The corner-sharing octahedral tilt angles are 13°. There are a spread of Mn–O bond distances ranging from 1.86–2.02 Å. In the third Mn4+ site, Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with two equivalent LiO4 tetrahedra, edges with three equivalent LiO6 octahedra, and edges with five MnO6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are a spread of Mn–O bond distances ranging from 1.89–2.00 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Mn4+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Mn4+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two Mn4+ atoms. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Mn4+ atoms. In the fifth O2- site, O2- is bonded to two equivalent Li1+ and three Mn4+ atoms to form OLi2Mn3 square pyramids that share corners with four OLi2Mn2 tetrahedra, an edgeedge with one OLi2Mn3 square pyramid, and edges with two OLi2Mn2 tetrahedra. In the sixth O2- site, O2- is bonded to two Li1+ and two Mn4+ atoms to form OLi2Mn2 tetrahedra that share corners with two equivalent OLi2Mn3 square pyramids, corners with three equivalent OLi2Mn2 tetrahedra, and an edgeedge with one OLi2Mn3 square pyramid. In the seventh O2- site, O2- is bonded to two Li1+ and two Mn4+ atoms to form distorted OLi2Mn2 tetrahedra that share corners with two equivalent OLi2Mn3 square pyramids, corners with three equivalent OLi2Mn2 tetrahedra, and an edgeedge with one OLi2Mn3 square pyramid.« less
