The crystal structure described by NaCuO is half-Heusler structured and crystallizes in the cubic F-43m space group. Na(1) is bonded to six equivalent Cu(1) and four equivalent O(1) atoms to form distorted NaCu6O4 tetrahedra that share corners with four equivalent Cu(1)Na6O4 tetrahedra, corners with six equivalent Na(1)Cu6O4 tetrahedra, edges with six equivalent Cu(1)Na6O4 tetrahedra, and faces with twelve equivalent Na(1)Cu6O4 tetrahedra. Cu(1) is bonded to six equivalent Na(1) and four equivalent O(1) atoms to form distorted CuNa6O4 tetrahedra that share corners with four equivalent Na(1)Cu6O4 tetrahedra, corners with six equivalent Cu(1)Na6O4 tetrahedra, edges with six equivalent Na(1)Cu6O4 tetrahedra, and faces with twelve equivalent Cu(1)Na6O4 tetrahedra. O(1) is bonded in a body-centered cubic geometry to four equivalent Na(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
