Title: Materials Data on Li3Mn2(SiO4)2 by Materials Project

Abstract

Li3Mn2(SiO4)2 is Clathrate-derived structured and crystallizes in the monoclinic C2 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 LiO4 tetrahedra, corners with two equivalent MnO4 tetrahedra, corners with four SiO4 tetrahedra, and an edgeedge with one MnO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.91–2.07 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with two equivalent SiO4 tetrahedra, corners with four equivalent LiO4 tetrahedra, corners with four equivalent MnO4 tetrahedra, and an edgeedge with one SiO4 tetrahedra. There are two shorter (2.07 Å) and two longer (2.08 Å) Li–O bond lengths. Mn+2.50+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with four LiO4 tetrahedra, corners with four SiO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.96–2.08 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that sharemore » corners with four equivalent LiO4 tetrahedra, corners with four equivalent MnO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There is two shorter (1.64 Å) and two longer (1.66 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent MnO4 tetrahedra and corners with six LiO4 tetrahedra. There is two shorter (1.64 Å) and two longer (1.67 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn+2.50+, and one Si4+ atom. In the second O2- site, O2- is bonded to two Li1+, one Mn+2.50+, and one Si4+ atom to form edge-sharing OLi2MnSi tetrahedra. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Mn+2.50+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one Mn+2.50+, and one Si4+ atom.« less
