(Na)2NaCd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one disodium molecule and one NaCd cluster. In the NaCd cluster, Na(2) is bonded in a single-bond geometry to one Cd(1) atom. The Na(2)-Cd(1) bond length is 1.17 Å. Cd(1) is bonded in a single-bond geometry to one Na(2) atom.
