NaIrCd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaIrCd clusters. Na(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. The Na(1)-Cd(1) bond length is 0.55 Å. Ir(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. The Ir(1)-Cd(1) bond length is 0.18 Å. Cd(1) is bonded in a linear geometry to one Na(1) and one Ir(1) atom.
