SrTa2W crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrTa2W cluster. Sr(1) is bonded in a 2-coordinate geometry to one Ta(1) and one W(1) atom. The Sr(1)-Ta(1) bond length is 1.01 Å. The Sr(1)-W(1) bond length is 1.43 Å. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 2-coordinate geometry to one Sr(1) and one W(1) atom. The Ta(1)-W(1) bond length is 1.53 Å. In the second Ta site, Ta(2) is bonded in a distorted single-bond geometry to one W(1) atom. The Ta(2)-W(1) bond length is 1.53 Å. W(1) is bonded in a 3-coordinate geometry to one Sr(1), one Ta(1), and one Ta(2) atom.
