The crystal structure described by CdV2O4 is Spinel structured and crystallizes in the monoclinic C2/m space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent V(1)O6 octahedra, edges with two equivalent V(2)O6 octahedra, and edges with two equivalent V(3)O6 octahedra. In the second V site, V(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form VO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent V(3)O6 octahedra, and edges with four equivalent V(1)O6 octahedra. In the third V site, V(3) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form VO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra, edges with two equivalent V(2)O6 octahedra, and edges with four equivalent V(1)O6 octahedra. Cd(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form CdO4 tetrahedra that share corners with three equivalent V(2)O6 octahedra, corners with three equivalent V(3)O6 octahedra, and corners with six equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 60-61°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one V(1), one V(2), one V(3), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OV3Cd tetrahedra. In the second O site, O(2) is bonded to one V(2), two equivalent V(1), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OV3Cd tetrahedra. In the third O site, O(3) is bonded to one V(3), two equivalent V(1), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OV3Cd tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
