Materials Data on Li3Bi(BO3)2 by Materials Project

Abstract

Li3Bi(BO3)2 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 BiO5 trigonal bipyramids, and an edgeedge with one LiO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.88–2.20 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share a cornercorner with one LiO4 tetrahedra, an edgeedge with one LiO4 tetrahedra, and edges with two equivalent BiO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 2.10–2.62 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 1.89–2.42 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 one shorter (1.38 Å) and two longer (1.40 Å) B–O bond length. Bi3+ is bonded to five O2- atoms to form distorted BiO5 trigonal bipyramids that share corners with three equivalent LiO4 tetrahedra and edges with two equivalent LiO5 trigonal bipyramids. There are a spread of Bi–O bond distances ranging from 2.25–2.44 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 Bi3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one B3+, and one Bi3+ 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 Bi3+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one B3+, and one Bi3+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+, one B3+, and one Bi3+ atom.
