YRhCd2 crystallizes in the trigonal R3m space group. Y(1) is bonded in a 1-coordinate geometry to four equivalent Rh(1) and one Cd(1) atom. There are three shorter (2.92 Å) and one longer (3.24 Å) Y(1)-Rh(1) bond length. The Y(1)-Cd(1) bond length is 2.26 Å. Rh(1) is bonded in a 11-coordinate geometry to four equivalent Y(1), three equivalent Cd(1), and four equivalent Cd(2) atoms. All Rh(1)-Cd(1) bond lengths are 3.20 Å. There are three shorter (2.92 Å) and one longer (3.24 Å) Rh(1)-Cd(2) bond length. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Y(1) and three equivalent Rh(1) atoms. In the second Cd site, Cd(2) is bonded in a 4-coordinate geometry to four equivalent Rh(1) atoms.
