Materials Data on BaLiBO3 by Materials Project

Abstract

LiBaBO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing LiO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 2.00–2.23 Å. Ba2+ is bonded in a 6-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.29 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.39 Å) and one longer (1.40 Å) B–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, three equivalent Ba2+, and one B3+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+, three equivalent Ba2+, and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Li1+, three equivalent Ba2+, and one B3+ atom.
