SrCdGa2 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent Cd(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. There is one shorter (1.70 Å) and one longer (3.48 Å) Sr(1)-Cd(1) bond length. There is one shorter (1.54 Å) and one longer (3.37 Å) Sr(1)-Ga(1) bond length. There is one shorter (2.27 Å) and one longer (2.91 Å) Sr(1)-Ga(2) bond length. Cd(1) is bonded in a 2-coordinate geometry to two equivalent Sr(1), one Ga(1), and two equivalent Ga(2) atoms. The Cd(1)-Ga(1) bond length is 1.46 Å. There is one shorter (2.17 Å) and one longer (3.34 Å) Cd(1)-Ga(2) bond length. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to two equivalent Sr(1), one Cd(1), and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 2.01 Å. In the second Ga site, Ga(2) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent Cd(1), and one Ga(1) atom.
