Materials Data on CsB5O8 by Materials Project

Abstract

CsB5O8 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.03–3.26 Å. There are five 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 1.35–1.40 Å. In the second B3+ site, B3+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of B–O bond distances ranging from 1.47–1.50 Å. In the third 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 1.36–1.40 Å. In the fourth 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 1.35–1.40 Å. In the fifth 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 1.35–1.41 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+ and two B3+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two B3+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+ and two B3+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two B3+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two B3+ atoms. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Cs1+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+ and two B3+ atoms.
