Materials Data on Au2O3 by Materials Project
Au2O3 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Au3+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Au–O bond distances ranging from 1.99–2.11 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent Au3+ atoms. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to three equivalent Au3+ atoms.
