Materials Data on KCuO2 by Materials Project
KCuO2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are two shorter (2.69 Å) and four longer (2.84 Å) K–O bond lengths. Cu3+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.85 Å. O2- is bonded in a 5-coordinate geometry to three equivalent K1+ and two equivalent Cu3+ atoms.
