Rh3Sn2S2 crystallizes in the trigonal R-3m space group. Rh(1) is bonded to two equivalent Sn(1), two equivalent Sn(2), and two equivalent S(1) atoms to form distorted RhSn4S2 octahedra that share corners with two equivalent Sn(2)Rh6S2 hexagonal bipyramids, corners with twelve equivalent Rh(1)Sn4S2 octahedra, and faces with four equivalent Rh(1)Sn4S2 octahedra. The corner-sharing octahedral tilt angles range from 0-62°. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted hexagonal planar geometry to six equivalent Rh(1) atoms. In the second Sn site, Sn(2) is bonded to six equivalent Rh(1) and two equivalent S(1) atoms to form SnRh6S2 hexagonal bipyramids that share corners with six equivalent Sn(2)Rh6S2 hexagonal bipyramids and corners with six equivalent Rh(1)Sn4S2 octahedra. The corner-sharing octahedral tilt angles are 46°. S(1) is bonded in a 4-coordinate geometry to three equivalent Rh(1) and one Sn(2) atom.
