RuIrCd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuIrCd clusters. Ru(1) is bonded in a single-bond geometry to one Cd(1) atom. The Ru(1)-Cd(1) bond length is 2.06 Å. Ir(1) is bonded in a single-bond geometry to one Cd(1) atom. The Ir(1)-Cd(1) bond length is 0.76 Å. Cd(1) is bonded in a distorted single-bond geometry to one Ru(1) and one Ir(1) atom.
