NaIr(Sn)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one distannene molecule and one NaIr cluster. In the NaIr cluster, Na(1) is bonded in a single-bond geometry to one Ir(1) atom. The Na(1)-Ir(1) bond length is 0.59 Å. Ir(1) is bonded in a single-bond geometry to one Na(1) atom.
