Materials Data on Cu3O2 by Materials Project
Cu3O2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Cu+1.33+ sites. In the first Cu+1.33+ site, Cu+1.33+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.84 Å. In the second Cu+1.33+ site, Cu+1.33+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 2.02 Å. O2- is bonded in a square co-planar geometry to four Cu+1.33+ atoms.
