Materials Data on K2CuI2O by Materials Project
K2CuOI2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded in a square co-planar geometry to two equivalent O2- and two equivalent I1- atoms. Both K–O bond lengths are 2.67 Å. Both K–I bond lengths are 3.33 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent I1- atoms. All Cu–I bond lengths are 2.67 Å. O2- is bonded in a square co-planar geometry to four equivalent K1+ atoms. I1- is bonded in a square co-planar geometry to two equivalent K1+ and two equivalent Cu2+ atoms.
