RhBiSb crystallizes in the trigonal R3m space group. Rh(1) is bonded in a single-bond geometry to one Bi(1) and three equivalent Sb(1) atoms. The Rh(1)-Bi(1) bond length is 0.45 Å. All Rh(1)-Sb(1) bond lengths are 2.70 Å. Bi(1) is bonded in a single-bond geometry to one Rh(1) and four equivalent Sb(1) atoms. There are three shorter (2.72 Å) and one longer (3.52 Å) Bi(1)-Sb(1) bond length. Sb(1) is bonded to three equivalent Rh(1) and four equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing SbBi4Rh3 hexagonal pyramids.
