Materials Data on LiBi4B3O11 by Materials Project
LiB3Bi4O11 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded in a trigonal pyramidal geometry to four O2- atoms. There are two shorter (2.06 Å) and two longer (2.12 Å) Li–O bond lengths. 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 1.38–1.40 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.41 Å) B–O bond length. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.13–2.26 Å. In the second Bi3+ site, Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.14–2.96 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one B3+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Bi3+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and two Bi3+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one B3+ and two Bi3+ atoms. In the sixth O2- site, O2- is bonded in a single-bond geometry to one B3+ and two equivalent Bi3+ atoms.
