Cr4CuCdO8 is Spinel-derived structured and crystallizes in the cubic F-43m space group. Cr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CrO6 octahedra that share corners with three equivalent Cu(1)O4 tetrahedra, corners with three equivalent Cd(1)O4 tetrahedra, and edges with six equivalent Cr(1)O6 octahedra. Cu(1) is bonded to four equivalent O(2) atoms to form CuO4 tetrahedra that share corners with twelve equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Cd(1) is bonded to four equivalent O(1) atoms to form CdO4 tetrahedra that share corners with twelve equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 61°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Cr(1) and one Cd(1) atom to form OCr3Cd tetrahedra that share corners with three equivalent O(1)Cr3Cd tetrahedra, corners with nine equivalent O(2)Cr3Cu trigonal pyramids, and edges with three equivalent O(1)Cr3Cd tetrahedra. In the second O site, O(2) is bonded to three equivalent Cr(1) and one Cu(1) atom to form distorted OCr3Cu trigonal pyramids that share corners with nine equivalent O(1)Cr3Cd tetrahedra, corners with three equivalent O(2)Cr3Cu trigonal pyramids, and edges with three equivalent O(2)Cr3Cu trigonal pyramids.
