The structure described by Cd(CoO2)2 is Spinel structured and crystallizes in the triclinic P-1 space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted CoO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Co(3)O6 octahedra, and edges with two equivalent Co(4)O6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(3)O6 octahedra, and edges with two equivalent Co(4)O6 octahedra. In the third Co site, Co(3) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted CoO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, and edges with two equivalent Co(4)O6 octahedra. In the fourth Co site, Co(4) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted CoO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, and edges with two equivalent Co(3)O6 octahedra. Cd(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CdO4 tetrahedra that share corners with three equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O6 octahedra, corners with three equivalent Co(3)O6 octahedra, and corners with three equivalent Co(4)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-68°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Co(1), one Co(2), one Co(4), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OCdCo3 tetrahedra. In the second O site, O(2) is bonded to one Co(1), one Co(2), one Co(3), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OCdCo3 tetrahedra. In the third O site, O(3) is bonded to one Co(1), one Co(3), one Co(4), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OCdCo3 tetrahedra. In the fourth O site, O(4) is bonded to one Co(2), one Co(3), one Co(4), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OCdCo3 tetrahedra. is represented by the CIF file [CIF]
