SrCdGa2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrCdGa2 cluster. Sr(1) is bonded in a distorted L-shaped geometry to one Cd(1) and one Ga(1) atom. The Sr(1)-Cd(1) bond length is 1.68 Å. The Sr(1)-Ga(1) bond length is 1.88 Å. Cd(1) is bonded in a 1-coordinate geometry to one Sr(1) and one Ga(2) atom. The Cd(1)-Ga(2) bond length is 1.88 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 1.68 Å. In the second Ga site, Ga(2) is bonded in an L-shaped geometry to one Cd(1) and one Ga(1) atom.
