The Materials Project

K2CuO2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. K1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.46 Å) and one longer (2.47 Å) K–O bond lengths. Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.11 Å) and two longer (2.14 Å) Cu–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a square co-planar geometry to two equivalent K1+ and two equivalent Cu2+ atoms. In the second O2- site, O2- is bonded in a square co-planar geometry to two equivalent K1+ and two equivalent Cu2+ atoms.
