title: Materials Data on Li3Mn3CoO8 by Materials Project

description: Li3Mn3CoO8 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 six O2- atoms to form LiO6 octahedra that share corners with seven MnO6 octahedra, edges with two MnO6 octahedra, edges with two equivalent CoO6 octahedra, edges with four LiO6 octahedra, and a faceface with one MnO6 octahedra. The corner-sharing octahedra tilt angles range from 9–51°. There are a spread of Li–O bond distances ranging from 2.03–2.27 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with seven MnO6 octahedra, edges with two equivalent MnO6 octahedra, edges with two equivalent CoO6 octahedra, edges with four equivalent LiO6 octahedra, and a faceface with one MnO6 octahedra. The corner-sharing octahedra tilt angles range from 5–50°. There are a spread of Li–O bond distances ranging from 1.97–2.31 Å. 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 CoO6 octahedra, corners with seven LiO6 octahedra, an edgeedge with one CoO6 octahedra, edges with two LiO6 octahedra, edges with four MnO6 octahedra, and a faceface with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 9–53°. There are a spread of Mn–O bond distances ranging from 1.94–1.99 Å. In the second Mn+3.67+ site, Mn+3.67+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with seven LiO6 octahedra, an edgeedge with one CoO6 octahedra, edges with two equivalent LiO6 octahedra, edges with four equivalent MnO6 octahedra, and a faceface with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 5–56°. There are a spread of Mn–O bond distances ranging from 1.98–2.19 Å. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six MnO6 octahedra, edges with three MnO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 52–56°. There are a spread of Co–O bond distances ranging from 2.05–2.18 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+, two equivalent Mn+3.67+, and one Co2+ atom to form distorted OLi2Mn2Co trigonal bipyramids that share corners with seven OLi2Mn2Co square pyramids, edges with two equivalent OLi3Mn3 octahedra, and edges with two equivalent OLi2Mn2Co square pyramids. In the second O2- site, O2- is bonded to three Li1+ and three Mn+3.67+ atoms to form edge-sharing OLi3Mn3 octahedra. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two Li1+, two Mn+3.67+, and one Co2+ atom. In the fourth O2- site, O2- is bonded to two equivalent Li1+, two equivalent Mn+3.67+, and one Co2+ atom to form OLi2Mn2Co square pyramids that share corners with two equivalent OLi2Mn2Co square pyramids, corners with five equivalent OLi2Mn2Co trigonal bipyramids, edges with two equivalent OLi3Mn3 octahedra, and edges with two equivalent OLi2Mn2Co square pyramids. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to three Li1+ and three Mn+3.67+ atoms. In the sixth O2- site, O2- is bonded to two Li1+, two Mn+3.67+, and one Co2+ atom to form OLi2Mn2Co square pyramids that share corners with two OLi2Mn2Co square pyramids, a cornercorner with one OLi2Mn2Co trigonal bipyramid, edges with two equivalent OLi3Mn3 octahedra, edges with two OLi2Mn2Co square pyramids, and an edgeedge with one OLi2Mn2Co trigonal bipyramid.
