The material structure described by Sr2CdWO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-29°. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-29°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1), one W(1), and one Cd(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1), one W(1), and one Cd(1) atom to form a mixture of distorted corner and edge-sharing OSr4CdW octahedra. The corner-sharing octahedral tilt angles range from 0-6°. is represented by the CIF file [CIF]
