RbSnS2 is Caswellsilverite-like structured and crystallizes in the trigonal R3m space group. Rb(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. Sn(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form edge-sharing SnS6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to three equivalent Rb(1) and three equivalent Sn(1) atoms to form a mixture of distorted face, corner, and edge-sharing SRb3Sn3 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 0-41°. In the second S site, S(2) is bonded to three equivalent Rb(1) and three equivalent Sn(1) atoms to form a mixture of face, corner, and edge-sharing SRb3Sn3 octahedra.
