The compound described by Rh3Si2Bi2 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 6-coordinate geometry to two equivalent Si(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. In the second Rh site, Rh(2) is bonded in a 2-coordinate geometry to two equivalent Si(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to two equivalent Si(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. Si(1) is bonded in a 3-coordinate geometry to one Rh(1), one Rh(2), one Rh(3), and one Bi(2) atom. 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 8-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Rh(3), and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
