Materials Data on LiBiB2O5 by Materials Project

Abstract

LiB2BiO5 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Li1+ is bonded in a distorted trigonal pyramidal geometry to four O2- atoms. There is two shorter (1.96 Å) and two longer (2.03 Å) Li–O bond length. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.41 Å. Bi3+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Bi–O bond distances ranging from 2.43–2.88 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one B3+, and two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Li1+, one B3+, and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent B3+ and two equivalent Bi3+ atoms.
