Materials Data on Li3B2SbO6 by Materials Project

Abstract

Li3B2SbO6 crystallizes in the monoclinic P2_1/c 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 LiO5 trigonal bipyramid, corners with three equivalent SbO5 trigonal bipyramids, and an edgeedge with one LiO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.90–2.18 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 trigonal bipyramids that share a cornercorner with one LiO4 tetrahedra, an edgeedge with one LiO4 tetrahedra, and edges with two equivalent SbO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 2.07–2.50 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.91–2.35 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 is one shorter (1.39 Å) and two longer (1.40 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.39 Å) and one longer (1.41 Å) B–O bond length. Sb3+ is bonded to five O2- atoms to form SbO5 trigonal bipyramids that share corners with three equivalent LiO4 tetrahedra and edges with two equivalent LiO5 trigonal bipyramids. There are a spread of Sb–O bond distances ranging from 2.14–2.43 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one B3+, and one Sb3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one B3+, and one Sb3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to four Li1+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one B3+, and one Sb3+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one B3+, and one Sb3+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+, one B3+, and one Sb3+ atom.
