The compound described by KY(CuO2)2 crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Y(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent K(1), two equivalent Y(1), and two equivalent Cu(1) atoms to form a mixture of distorted corner, face, and edge-sharing OK2Y2Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-69°. is represented by the CIF card [CIF]
