(CuO2)(Y)(CuO2) is Spinel structured and crystallizes in the cubic Fd-3m space group. Y(1) is bonded to four equivalent O(1) atoms to form YO4 tetrahedra that share corners with twelve equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Cu(1) is bonded to six equivalent O(1) atoms to form CuO6 octahedra that share corners with six equivalent Y(1)O4 tetrahedra and edges with six equivalent Cu(1)O6 octahedra. O(1) is bonded to one Y(1) and three equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OYCu3 tetrahedra.
