Materials Data on Bi2O5 by Materials Project
Bi2O5 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Bi5+ sites. In the first Bi5+ site, Bi5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 3–32°. There are a spread of Bi–O bond distances ranging from 2.06–2.24 Å. In the second Bi5+ site, Bi5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 3–32°. There are a spread of Bi–O bond distances ranging from 2.06–2.24 Å. In the third Bi5+ site, Bi5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–32°. There are a spread of Bi–O bond distances ranging from 2.06–2.24 Å. In the fourth Bi5+ site, Bi5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–32°. There are a spread of Bi–O bond distances ranging from 2.06–2.24 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Bi5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Bi5+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Bi5+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Bi5+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to two equivalent Bi5+ atoms. In the sixth O2- site, O2- is bonded in a linear geometry to two equivalent Bi5+ atoms. In the seventh O2- site, O2- is bonded in a linear geometry to two equivalent Bi5+ atoms. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to two Bi5+ atoms. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to two Bi5+ atoms. In the tenth O2- site, O2- is bonded in a linear geometry to two equivalent Bi5+ atoms.
