Ga(Nb)(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 Cd clusters and two Ga(Nb) 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 0.53 Å. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Cd(1) atom. In each Ga(Nb) cluster, Nb(1) is bonded in a single-bond geometry to one Ga(1) atom. The Nb(1)-Ga(1) bond length is 0.64 Å. Ga(1) is bonded in a single-bond geometry to one Nb(1) atom.
