Materials Data on Bi2O3 by Materials Project

Abstract

Bi2O3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Bi3+ sites. In the first 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 2.26–2.66 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 2.20–2.75 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 2.24–2.73 Å. In the fourth Bi3+ site, Bi3+ is bonded to five O2- atoms to form corner-sharing BiO5 trigonal bipyramids. There are a spread of Bi–O bond distances ranging from 2.23–2.38 Å. In the fifth Bi3+ site, Bi3+ is bonded to five O2- atoms to form corner-sharing BiO5 trigonal bipyramids. There are a spread of Bi–O bond distances ranging from 2.24–2.37 Å. In the sixth 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 2.21–2.81 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Bi3+ atoms. In the second O2- site, O2- is bonded to four Bi3+ atoms to form distorted corner-sharing OBi4 tetrahedra. In the third O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi3+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Bi3+ atoms. In the fifth O2- site, O2- is bonded to four Bi3+ atoms to form distorted corner-sharing OBi4 tetrahedra. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi3+ atoms. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three Bi3+ atoms. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to four Bi3+ atoms. In the ninth O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi3+ atoms.
