Materials Data on Li3MnCoNiO6 by Materials Project
Li3MnCoNiO6 is beta Polonium-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with two equivalent CoO6 octahedra, corners with two equivalent NiO6 octahedra, edges with two equivalent MnO6 octahedra, edges with two equivalent CoO6 octahedra, edges with two equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–8°. There are a spread of Li–O bond distances ranging from 2.11–2.22 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with two equivalent CoO6 octahedra, corners with two equivalent NiO6 octahedra, edges with two equivalent MnO6 octahedra, edges with two equivalent CoO6 octahedra, edges with two equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–8°. There are a spread of Li–O bond distances ranging from 2.06–2.22 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with two equivalent CoO6 octahedra, corners with two equivalent NiO6 octahedra, edges with two equivalent MnO6 octahedra, edges with two equivalent CoO6 octahedra, edges with two equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 3–8°. There are a spread of Li–O bond distances ranging from 2.09–2.21 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six LiO6 octahedra, edges with three equivalent CoO6 octahedra, edges with three equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are a spread of Mn–O bond distances ranging from 1.93–1.96 Å. Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six LiO6 octahedra, edges with three equivalent MnO6 octahedra, edges with three equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 7–8°. There are a spread of Co–O bond distances ranging from 1.99–2.05 Å. Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six LiO6 octahedra, edges with three equivalent MnO6 octahedra, edges with three equivalent CoO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are four shorter (2.08 Å) and two longer (2.10 Å) Ni–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, one Mn2+, one Co3+, and one Ni4+ atom to form a mixture of corner and edge-sharing OLi3MnCoNi octahedra. The corner-sharing octahedra tilt angles range from 3–5°. In the second O2- site, O2- is bonded to three Li1+, one Mn2+, one Co3+, and one Ni4+ atom to form a mixture of corner and edge-sharing OLi3MnCoNi octahedra. The corner-sharing octahedra tilt angles range from 2–5°. In the third O2- site, O2- is bonded to three Li1+, one Mn2+, one Co3+, and one Ni4+ atom to form a mixture of corner and edge-sharing OLi3MnCoNi octahedra. The corner-sharing octahedra tilt angles range from 2–7°.
