Sb2Te3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sb3+ is bonded in a linear geometry to two Te2- atoms. There are one shorter (2.90 Å) and one longer (3.17 Å) Sb–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to two equivalent Sb3+ and six equivalent Te2- atoms to form a mixture of edge and corner-sharing TeSb2Te6 hexagonal bipyramids. All Te–Te bond lengths are 3.39 Å. In the second Te2- site, Te2- is bonded to one Sb3+ and seven equivalent Te2- atoms to form distorted TeSbTe7 hexagonal bipyramids that share corners with seven TeSb2Te6 hexagonal bipyramids and edges with eighteen equivalent TeSbTe7 hexagonal bipyramids. There are six shorter (3.39 Å) and one longer (3.48 Å) Te–Te bond lengths.
