SrYGa4 is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three SrYGa4 clusters. Sr(1) is bonded in a single-bond geometry to one Y(1) atom. The Sr(1)-Y(1) bond length is 0.32 Å. Y(1) is bonded in a distorted rectangular see-saw-like geometry to one Sr(1) and three equivalent Ga(1) atoms. All Y(1)-Ga(1) bond lengths are 0.28 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 3-coordinate geometry to three equivalent Ga(1) atoms. All Ga(2)-Ga(1) bond lengths are 0.18 Å. In the second Ga site, Ga(1) is bonded in a 3-coordinate geometry to one Y(1), one Ga(2), and two equivalent Ga(1) atoms. Both Ga(1)-Ga(1) bond lengths are 0.10 Å.
