Materials Data on Li2BiBO4 by Materials Project

Li2BBiO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra and corners with four equivalent BO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.10 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with eight equivalent LiO4 tetrahedra. There is two shorter (1.46 Å) and two longer (1.56 Å) B–O bond length. Bi3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Bi–O bond distances ranging from 2.18–2.65 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one B3+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a distorted tetrahedral geometry to two equivalent Li1+, one B3+, and one Bi3+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+, one B3+, and two equivalent Bi3+ atoms.

In the second Li1+ site, Li1+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.92–2.06 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.43 Å. Bi3+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Bi–O bond distances ranging from 2.19–2.47 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and one B3+ atom to form corner-sharing OLi3B tetrahedra. 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 2-coordinate geometry to one Li1+, one B3+, and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+ and two equivalent Bi3+ atoms.
