Materials Data on Li2MnSnO4 by Materials Project
Li2MnSnO4 is alpha Po-derived structured and crystallizes in the monoclinic C2/c 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 six equivalent MnO6 octahedra, edges with two equivalent MnO6 octahedra, edges with four equivalent SnO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are a spread of Li–O bond distances ranging from 2.17–2.28 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent SnO6 octahedra, edges with two equivalent SnO6 octahedra, edges with four equivalent MnO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–5°. There are a spread of Li–O bond distances ranging from 2.25–2.34 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent MnO6 octahedra, edges with four equivalent SnO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are a spread of Mn–O bond distances ranging from 2.20–2.23 Å. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent SnO6 octahedra, edges with four equivalent MnO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–5°. There are two shorter (2.07 Å) and four longer (2.15 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, two equivalent Mn2+, and one Sn4+ atom to form a mixture of corner and edge-sharing OLi3Mn2Sn octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to three Li1+, one Mn2+, and two equivalent Sn4+ atoms to form OLi3MnSn2 octahedra that share corners with six equivalent OLi3MnSn2 octahedra and edges with twelve OLi3Mn2Sn octahedra. The corner-sharing octahedral tilt angles are 0°.
