Materials Data on Bi2AuO5 by Materials Project
AuBi2O5 crystallizes in the tetragonal P4/ncc space group. The structure is three-dimensional. Au2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.01 Å. Bi4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.35–2.60 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Au2+ and three equivalent Bi4+ atoms. In the second O2- site, O2- is bonded to four equivalent Bi4+ atoms to form edge-sharing OBi4 tetrahedra.
