W2SbTe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2SbTe clusters. There are two inequivalent W sites. In the first W site, W(1) is bonded in a linear geometry to one Sb(1) and one Te(1) atom. The W(1)-Sb(1) bond length is 1.08 Å. The W(1)-Te(1) bond length is 1.16 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Te(1) atom. The W(2)-Te(1) bond length is 0.05 Å. Sb(1) is bonded in a single-bond geometry to one W(1) atom. Te(1) is bonded in a distorted linear geometry to one W(1) and one W(2) atom.
