The structure described by KCuO is half-Heusler structured and crystallizes in the cubic F-43m space group. K(1) is bonded to six equivalent Cu(1) and four equivalent O(1) atoms to form distorted KCu6O4 tetrahedra that share corners with four equivalent Cu(1)K6O4 tetrahedra, corners with six equivalent K(1)Cu6O4 tetrahedra, edges with six equivalent Cu(1)K6O4 tetrahedra, and faces with twelve equivalent K(1)Cu6O4 tetrahedra. Cu(1) is bonded to six equivalent K(1) and four equivalent O(1) atoms to form distorted CuK6O4 tetrahedra that share corners with four equivalent K(1)Cu6O4 tetrahedra, corners with six equivalent Cu(1)K6O4 tetrahedra, edges with six equivalent K(1)Cu6O4 tetrahedra, and faces with twelve equivalent Cu(1)K6O4 tetrahedra. O(1) is bonded in a body-centered cubic geometry to four equivalent K(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
