SrW5 is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrW5 cluster. Sr(1) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one W(5) atom. The Sr(1)-W(1) bond length is 1.84 Å. The Sr(1)-W(2) bond length is 1.37 Å. The Sr(1)-W(5) bond length is 1.40 Å. There are five inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one Sr(1) and one W(3) atom. The W(1)-W(3) bond length is 1.46 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Sr(1) atom. In the third W site, W(3) is bonded in a bent 120 degrees geometry to one W(1) and one W(4) atom. The W(3)-W(4) bond length is 1.07 Å. In the fourth W site, W(4) is bonded in a 1-coordinate geometry to one W(3) atom. In the fifth W site, W(5) is bonded in a single-bond geometry to one Sr(1) atom.
