IrRhAuCd crystallizes in the trigonal R3m space group. Ir(1) is bonded in a 7-coordinate geometry to one Rh(1), three equivalent Au(1), and three equivalent Cd(1) atoms. The Ir(1)-Rh(1) bond length is 2.45 Å. All Ir(1)-Au(1) bond lengths are 2.70 Å. All Ir(1)-Cd(1) bond lengths are 2.70 Å. Rh(1) is bonded in a distorted single-bond geometry to one Ir(1), three equivalent Au(1), and one Cd(1) atom. All Rh(1)-Au(1) bond lengths are 2.70 Å. The Rh(1)-Cd(1) bond length is 1.90 Å. Au(1) is bonded in a 10-coordinate geometry to three equivalent Ir(1), three equivalent Rh(1), and four equivalent Cd(1) atoms. There is one shorter (2.45 Å) and three longer (2.92 Å) Au(1)-Cd(1) bond lengths. Cd(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1), one Rh(1), and four equivalent Au(1) atoms.
