The structure described by Rh3Bi2S2 crystallizes in the monoclinic C2/m space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to two equivalent Bi(1), two equivalent Bi(2), and two equivalent S(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and two equivalent Rh(3) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and two equivalent Rh(3) atoms. S(1) is bonded in a distorted T-shaped geometry to one Rh(1), one Rh(2), and one Rh(3) atom. is represented by the CIF file [CIF]
