Title: Materials Data on Li7Mn3(SiO6)2 by Materials Project

Abstract

Li7Mn3(SiO6)2 is Caswellsilverite-derived structured and crystallizes in the monoclinic C2/m 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 a cornercorner with one LiO6 octahedra, corners with two equivalent SiO6 octahedra, corners with three MnO6 octahedra, edges with two equivalent SiO6 octahedra, edges with three MnO6 octahedra, and edges with seven LiO6 octahedra. The corner-sharing octahedra tilt angles range from 7–14°. There are a spread of Li–O bond distances ranging from 2.07–2.16 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six LiO6 octahedra, edges with six LiO6 octahedra, and edges with six equivalent SiO6 octahedra. The corner-sharing octahedra tilt angles range from 12–17°. There are four shorter (2.08 Å) and two longer (2.19 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with two equivalent SiO6 octahedra, corners with three MnO6 octahedra, edges with two equivalent SiO6 octahedra, edges with three MnO6 octahedra, and edges withmore » seven LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–17°. There are a spread of Li–O bond distances ranging from 2.00–2.38 Å. There are two inequivalent Mn3+ sites. In the first Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six LiO6 octahedra, edges with six LiO6 octahedra, and edges with six equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are four shorter (1.94 Å) and two longer (2.25 Å) Mn–O bond lengths. In the second Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six LiO6 octahedra, edges with six LiO6 octahedra, and edges with six MnO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are a spread of Mn–O bond distances ranging from 1.94–2.23 Å. Si4+ is bonded to six O2- atoms to form SiO6 octahedra that share corners with six LiO6 octahedra, edges with three equivalent SiO6 octahedra, and edges with nine LiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–14°. There is four shorter (1.84 Å) and two longer (1.89 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and three Mn3+ atoms to form a mixture of edge and corner-sharing OLi3Mn3 octahedra. The corner-sharing octahedra tilt angles range from 0–9°. In the second O2- site, O2- is bonded to four Li1+ and two equivalent Si4+ atoms to form a mixture of distorted edge and corner-sharing OLi4Si2 octahedra. The corner-sharing octahedra tilt angles range from 0–12°. In the third O2- site, O2- is bonded to three Li1+ and three Mn3+ atoms to form a mixture of edge and corner-sharing OLi3Mn3 octahedra. The corner-sharing octahedra tilt angles range from 0–9°. In the fourth O2- site, O2- is bonded to four Li1+ and two equivalent Si4+ atoms to form a mixture of edge and corner-sharing OLi4Si2 octahedra. The corner-sharing octahedra tilt angles range from 0–12°.« less
