Materials Data on AgAuO2 by Materials Project

AuAgO2 crystallizes in the orthorhombic Pmna space group. The structure is three-dimensional. Au3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.05 Å. Ag1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. All Ag–O bond lengths are 2.34 Å. O2- is bonded to two equivalent Au3+ and two equivalent Ag1+ atoms to form a mixture of distorted corner and edge-sharing OAg2Au2 tetrahedra.

Materials Data on AgAuO2 by Materials Project

AuAgO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Au3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There are two shorter (2.04 Å) and two longer (2.05 Å) Au–O bond lengths. Ag1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.18 Å) and two longer (2.67 Å) Ag–O bond lengths. O2- is bonded to two equivalent Au3+ and two equivalent Ag1+ atoms to form a mixture of distorted edge and corner-sharing OAg2Au2 tetrahedra.
