The material described by Sr3CdO4 is Caswellsilverite-like structured and crystallizes in the cubic Pm-3m space group. Sr(1) is bonded to two equivalent O(1) and four O(2,2) atoms to form SrO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with four equivalent Cd(1)O6 octahedra, and edges with eight equivalent Sr(1)O6 octahedra. The corner-sharing octahedra are not tilted. Cd(1) is bonded to six O(2,2,2) atoms to form CdO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra and edges with twelve equivalent Sr(1)O6 octahedra. The corner-sharing octahedra are not tilted. There are four inequivalent O sites. In the first O site, O(1) is bonded to six equivalent Sr(1) atoms to form OSr6 octahedra that share corners with six equivalent O(1)Sr6 octahedra and edges with twelve O(2,2,2)Sr4Cd2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Cd(1) atoms to form OSr4Cd2 octahedra that share corners with six equivalent O(2)Sr4Cd2 octahedra; edges with four equivalent O(1)Sr6 octahedra; and edges with eight O(2,2)Sr4Cd2 octahedra. The corner-sharing octahedra are not tilted. In the third O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Cd(1) atoms to form OSr4Cd2 octahedra that share corners with six equivalent O(2)Sr4Cd2 octahedra; edges with four equivalent O(1)Sr6 octahedra; and edges with eight O(2,2)Sr4Cd2 octahedra. The corner-sharing octahedra are not tilted. In the fourth O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Cd(1) atoms to form OSr4Cd2 octahedra that share corners with six equivalent O(2)Sr4Cd2 octahedra; edges with four equivalent O(1)Sr6 octahedra; and edges with eight O(2,2)Sr4Cd2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
