Materials Data on Li3Sn(BO3)2 by Materials Project

Abstract

Li3Sn(BO3)2 crystallizes in the triclinic P-1 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 a cornercorner with one SnO4 tetrahedra, corners with four LiO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.08 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent SnO4 tetrahedra, corners with four LiO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.93–2.22 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two LiO4 tetrahedra, corners with three equivalent SnO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.10 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.35–1.43 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.35–1.42 Å. Sn3+ is bonded to four O2- atoms to form SnO4 tetrahedra that share corners with six LiO4 tetrahedra. There are a spread of Sn–O bond distances ranging from 2.02–2.27 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two Li1+, one B3+, and one Sn3+ atom to form distorted corner-sharing OLi2SnB tetrahedra. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one B3+, and one Sn3+ atom. In the third O2- site, O2- is bonded to three Li1+ and one B3+ atom to form distorted OLi3B tetrahedra that share corners with five OLi2SnB tetrahedra and an edgeedge with one OLi3B tetrahedra. In the fourth O2- site, O2- is bonded to two Li1+, one B3+, and one Sn3+ atom to form distorted OLi2SnB tetrahedra that share corners with six OLi2SnB tetrahedra and an edgeedge with one OLi3B tetrahedra. In the fifth O2- site, O2- is bonded to three Li1+ and one B3+ atom to form a mixture of distorted edge and corner-sharing OLi3B tetrahedra. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one B3+, and one Sn3+ atom.
