Cd Cd Bi Rh Rh
Rh2Cd2Bi crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 4-coordinate geometry to one Rh(1), one Cd(1), and two equivalent Cd(2) atoms. The Rh(1)-Rh(1) bond length is 1.50 Å. The Rh(1)-Cd(1) bond length is 1.82 Å. There is one shorter (2.85 Å) and one longer (3.37 Å) Rh(1)-Cd(2) bond length. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to two equivalent Rh(1) and one Bi(1) atom. The Cd(1)-Bi(1) bond length is 1.30 Å. In the second Cd site, Cd(2) is bonded in a single-bond geometry to four equivalent Rh(1) and one Bi(1) atom. The Cd(2)-Bi(1) bond length is 0.82 Å. Bi(1) is bonded in a linear geometry to one Cd(1) and one Cd(2) atom.
