CrCdBi2 crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a distorted single-bond geometry to one Bi(1) and one Bi(2) atom. The Cr(1)-Bi(1) bond length is 3.32 Å. The Cr(1)-Bi(2) bond length is 1.82 Å. Cd(1) is bonded in a distorted bent 120 degrees geometry to one Bi(2) and three equivalent Bi(1) atoms. The Cd(1)-Bi(2) bond length is 2.88 Å. There is one shorter (2.88 Å) and two longer (3.49 Å) Cd(1)-Bi(1) bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to one Cr(1), three equivalent Cd(1), and four equivalent Bi(1) atoms. All Bi(1)-Bi(1) bond lengths are 3.35 Å. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one Cr(1) and one Cd(1) atom.
