NaCo(Cd)2 is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cobalt;sodium molecules and two Cd clusters. In each Cd cluster, there are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Cd(2) atom. The Cd(1)-Cd(2) bond length is 0.84 Å. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Cd(1) atom.
