Materials Data on CuAgO2 by Materials Project

AgCuO2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ag1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are a spread of Ag–O bond distances ranging from 2.31–2.52 Å. Cu3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There is two shorter (1.88 Å) and two longer (1.90 Å) Cu–O bond length. O2- is bonded in a 2-coordinate geometry to three equivalent Ag1+ and two equivalent Cu3+ atoms.

Materials Data on CuAgO2 by Materials Project

AgCuO2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two AgCuO2 sheets oriented in the (1, 0, 0) direction. Ag1+ is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.17 Å. Cu3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.88 Å. O2- is bonded in a distorted trigonal non-coplanar geometry to one Ag1+ and two equivalent Cu3+ atoms.

Materials Data on CuAgO2 by Materials Project

AgCuO2 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. Ag1+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Ag–O bond lengths are 2.26 Å. Cu3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.90 Å. O2- is bonded to two equivalent Ag1+ and two equivalent Cu3+ atoms to form a mixture of distorted edge and corner-sharing OCu2Ag2 tetrahedra.
