The crystal structure described by RbTbS2 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 Tb(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Tb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 13°. Tb(1) is bonded to six equivalent S(1) atoms to form TbS6 octahedra that share corners with six equivalent Rb(1)S6 octahedra, edges with six equivalent Rb(1)S6 octahedra, and edges with six equivalent Tb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 13°. S(1) is bonded to three equivalent Rb(1) and three equivalent Tb(1) atoms to form a mixture of edge and corner-sharing SRb3Tb3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
