RhAu2Bi crystallizes in the trigonal R3m space group. Rh(1) is bonded in a single-bond geometry to one Au(1) and four equivalent Bi(1) atoms. The Rh(1)-Au(1) bond length is 0.99 Å. There are three shorter (2.79 Å) and one longer (3.58 Å) Rh(1)-Bi(1) bond length. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Rh(1) and three equivalent Bi(1) atoms. All Au(1)-Bi(1) bond lengths are 2.85 Å. In the second Au site, Au(2) is bonded in a 3-coordinate geometry to four equivalent Bi(1) atoms. There are three shorter (2.79 Å) and one longer (3.58 Å) Au(2)-Bi(1) bond length. Bi(1) is bonded in a 11-coordinate geometry to four equivalent Rh(1), three equivalent Au(1), and four equivalent Au(2) atoms.
