The material structure described by RbYbS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded to six equivalent S(1) atoms to form distorted RbS6 octahedra that share corners with six equivalent Yb(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Yb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 13°. Yb(1) is bonded to six equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Rb(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Yb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 13°. S(1) is bonded to three equivalent Rb(1) and three equivalent Yb(1) atoms to form a mixture of corner and edge-sharing SRb3Yb3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
