The compound described by CdSnAs2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Cd(1) is bonded to six equivalent As(1) atoms to form CdAs6 octahedra that share corners with six equivalent Sn(1)As6 octahedra, edges with six equivalent Cd(1)As6 octahedra, and edges with six equivalent Sn(1)As6 octahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to six equivalent As(1) atoms to form SnAs6 octahedra that share corners with six equivalent Cd(1)As6 octahedra, edges with six equivalent Cd(1)As6 octahedra, and edges with six equivalent Sn(1)As6 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to three equivalent Cd(1) and three equivalent Sn(1) atoms to form a mixture of corner and edge-sharing AsCd3Sn3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
