K2CdGa2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2CdGa2 clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Cd(1) atom. The K(1)-Cd(1) bond length is 0.82 Å. In the second K site, K(2) is bonded in a 3-coordinate geometry to one Cd(1) and two equivalent Ga(1) atoms. The K(2)-Cd(1) bond length is 1.16 Å. Both K(2)-Ga(1) bond lengths are 0.96 Å. Cd(1) is bonded in a linear geometry to one K(1) and one K(2) atom. Ga(1) is bonded in a distorted single-bond geometry to one K(2) atom.
