KDyS2 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 Dy(1)S6 octahedra, edges with six equivalent K(1)S6 octahedra, and edges with six equivalent Dy(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. Dy(1) is bonded to six equivalent S(1) atoms to form DyS6 octahedra that share corners with six equivalent K(1)S6 octahedra, edges with six equivalent K(1)S6 octahedra, and edges with six equivalent Dy(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. S(1) is bonded to three equivalent K(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SK3Dy3 octahedra. The corner-sharing octahedra are not tilted.
