Sb Sb Sb W
WSb3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WSb3 cluster. W(1) is bonded in a single-bond geometry to one Sb(2) atom. The W(1)-Sb(2) bond length is 2.12 Å. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 2-coordinate geometry to one Sb(2) and one Sb(3) atom. The Sb(1)-Sb(2) bond length is 2.04 Å. The Sb(1)-Sb(3) bond length is 1.71 Å. In the second Sb site, Sb(2) is bonded in a 1-coordinate geometry to one W(1), one Sb(1), and one Sb(3) atom. The Sb(2)-Sb(3) bond length is 2.03 Å. In the third Sb site, Sb(3) is bonded in a 2-coordinate geometry to one Sb(1) and one Sb(2) atom.
