The crystal structure described by Y2AsS is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Y(1) is bonded to three equivalent As(1) and three equivalent S(1) atoms to form a mixture of corner and edge-sharing YAs3S3 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to six equivalent Y(1) atoms to form AsY6 octahedra that share corners with six equivalent S(1)Y6 octahedra, edges with six equivalent As(1)Y6 octahedra, and edges with six equivalent S(1)Y6 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to six equivalent Y(1) atoms to form SY6 octahedra that share corners with six equivalent As(1)Y6 octahedra, edges with six equivalent As(1)Y6 octahedra, and edges with six equivalent S(1)Y6 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
