Sb3Te crystallizes in the monoclinic P2/m space group. The structure is zero-dimensional and consists of one tellurium, mol. (te2) molecule and two Sb clusters. In each Sb cluster, there are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Sb(2) atoms. Both Sb(1)-Sb(2) bond lengths are 1.08 Å. In the second Sb site, Sb(2) is bonded in a single-bond geometry to one Sb(1) atom.
