Materials Data on Cu2AgO4 by Materials Project
AgCu2O4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ag3+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.12 Å) and two longer (2.14 Å) Ag–O bond lengths. There are two inequivalent Cu+2.50+ sites. In the first Cu+2.50+ site, Cu+2.50+ is bonded in a square co-planar geometry to four O2- atoms. All Cu–O bond lengths are 1.87 Å. In the second Cu+2.50+ site, Cu+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.84 Å) and two longer (1.85 Å) Cu–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal non-coplanar geometry to one Ag3+ and two Cu+2.50+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Ag3+ and two Cu+2.50+ atoms.
