SrYW2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrYW2 clusters. Sr(1) is bonded in a single-bond geometry to one Y(1) and one W(1) atom. The Sr(1)-Y(1) bond length is 1.12 Å. The Sr(1)-W(1) bond length is 3.73 Å. Y(1) is bonded in a distorted single-bond geometry to one Sr(1) and one W(2) atom. The Y(1)-W(2) bond length is 0.01 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. In the second W site, W(2) is bonded in a single-bond geometry to one Y(1) atom.
