The crystal structure described by RbPrS2 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 Pr(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Pr(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. Pr(1) is bonded to six equivalent S(1) atoms to form PrS6 octahedra that share corners with six equivalent Rb(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Pr(1)S6 octahedra. The corner-sharing octahedral tilt angles are 11°. S(1) is bonded to three equivalent Rb(1) and three equivalent Pr(1) atoms to form a mixture of edge and corner-sharing SRb3Pr3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
