NaCd2Sb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaCd2Sb clusters. Na(1) is bonded in a single-bond geometry to one Cd(2) atom. The Na(1)-Cd(2) bond length is 0.33 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Sb(1) atom. The Cd(1)-Sb(1) bond length is 1.17 Å. In the second Cd site, Cd(2) is bonded in a distorted linear geometry to one Na(1) and one Sb(1) atom. The Cd(2)-Sb(1) bond length is 1.17 Å. Sb(1) is bonded in a linear geometry to one Cd(1) and one Cd(2) atom.
