The compound described by KCuO2 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Cu(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of distorted corner, face, and edge-sharing OK3Cu2 trigonal bipyramids. is represented by the CIF card [CIF]
