SrRhBi2 crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to one Rh(1) and three equivalent Bi(1) atoms. The Sr(1)-Rh(1) bond length is 1.40 Å. All Sr(1)-Bi(1) bond lengths are 3.10 Å. Rh(1) is bonded in a distorted linear geometry to one Sr(1) and one Bi(2) atom. The Rh(1)-Bi(2) bond length is 1.40 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to three equivalent Sr(1) and one Bi(2) atom to form distorted corner-sharing BiSr3Bi trigonal pyramids. The Bi(1)-Bi(2) bond length is 1.40 Å. In the second Bi site, Bi(2) is bonded in a distorted linear geometry to one Rh(1) and one Bi(1) atom.
