Materials Data on Ba2Bi6O11 by Materials Project
Ba2Bi6O11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ba2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ba–O bond distances ranging from 2.43–3.35 Å. There are three inequivalent Bi3+ sites. In the first 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 2.22–3.04 Å. In the second Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Bi–O bond distances ranging from 2.21–2.83 Å. In the third Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Bi–O bond distances ranging from 2.14–2.65 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four Bi3+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to four Bi3+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to four Bi3+ atoms. In the fifth O2- site, O2- is bonded to one Ba2+ and three equivalent Bi3+ atoms to form distorted corner-sharing OBaBi3 tetrahedra. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent Ba2+ and one Bi3+ atom.
