The material structure described by RbErS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. Er(1) is bonded to six equivalent S(1) atoms to form edge-sharing ErS6 octahedra. S(1) is bonded to three equivalent Rb(1) and three equivalent Er(1) atoms to form a mixture of corner and edge-sharing SRb3Er3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
