Materials Data on CsB3O5 by Materials Project
CsB3O5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.03–3.43 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.49 Å) B–O bond length. In the second 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 1.36–1.41 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 1.36–1.41 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Cs1+ and two B3+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees 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 bent 120 degrees geometry to two equivalent 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.
