The material structure described by Sr(CdSb)2 crystallizes in the trigonal P-3m1 space group. Sr(1) is bonded to six equivalent Sb(1) atoms to form SrSb6 octahedra that share corners with twelve equivalent Cd(1)Sb4 tetrahedra, edges with six equivalent Sr(1)Sb6 octahedra, and edges with six equivalent Cd(1)Sb4 tetrahedra. Cd(1) is bonded to four equivalent Sb(1) atoms to form CdSb4 tetrahedra that share corners with six equivalent Sr(1)Sb6 octahedra, corners with six equivalent Cd(1)Sb4 tetrahedra, edges with three equivalent Sr(1)Sb6 octahedra, and edges with three equivalent Cd(1)Sb4 tetrahedra. The corner-sharing octahedral tilt angles range from 17-54°. Sb(1) is bonded to three equivalent Sr(1) and four equivalent Cd(1) atoms to form a mixture of distorted corner and edge-sharing SbSr3Cd4 pentagonal bipyramids. is represented by the CIF card [CIF]
