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

Abstract

Li3Mn2(SiO4)2 is Clathrate-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are three 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 four MnO4 tetrahedra, and corners with four SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.10 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four MnO4 tetrahedra, corners with four SiO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.92–2.03 Å. In the third 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, an edgeedge with one LiO4 tetrahedra, and an edgeedge with one MnO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.14 Å. There are two inequivalent Mn+2.50+ sites. In the first Mn+2.50+ site, Mn+2.50+ is bonded to four O2- atoms to form MnO4 tetrahedra that sharemore » corners with four SiO4 tetrahedra and corners with six LiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.98–2.09 Å. In the second Mn+2.50+ site, 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 1.94–2.07 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four MnO4 tetrahedra and corners with six LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four MnO4 tetrahedra and corners with six LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.67 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 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 corner-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 trigonal planar geometry to one Li1+, one Mn+2.50+, and one Si4+ atom. In the fifth O2- site, O2- is bonded to two Li1+, one Mn+2.50+, and one Si4+ atom to form a mixture of distorted corner and edge-sharing OLi2MnSi tetrahedra. In the sixth O2- site, O2- is bonded to two Li1+, one Mn+2.50+, and one Si4+ atom to form a mixture of corner and edge-sharing OLi2MnSi tetrahedra. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Mn+2.50+, and one Si4+ atom. In the eighth O2- site, O2- is bonded to two Li1+, one Mn+2.50+, and one Si4+ atom to form a mixture of distorted corner and edge-sharing OLi2MnSi trigonal pyramids.« less
