The structure described by KYS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent S(1) atoms to form distorted KS6 octahedra that share corners with six equivalent Y(1)S6 octahedra, edges with six equivalent K(1)S6 octahedra, and edges with six equivalent Y(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. Y(1) is bonded to six equivalent S(1) atoms to form YS6 octahedra that share corners with six equivalent K(1)S6 octahedra, edges with six equivalent K(1)S6 octahedra, and edges with six equivalent Y(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. S(1) is bonded to three equivalent K(1) and three equivalent Y(1) atoms to form a mixture of corner and edge-sharing SK3Y3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
