Sb2Te3 crystallizes in the monoclinic C2/c space group. Sb(1) is bonded in a 5-coordinate geometry to two equivalent Te(2) and three equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 2-coordinate geometry to three equivalent Sb(1) atoms. In the second Te site, Te(2) is bonded in a see-saw-like geometry to four equivalent Sb(1) atoms.
Sb2Te3 crystallizes in the monoclinic C2/c space group. Sb(1) is bonded in a 5-coordinate geometry to two equivalent Te(2) and three equivalent Te(1) atoms. There is one shorter (3.03 Å) and one longer (3.29 Å) Sb(1)-Te(2) bond length. There are a spread of Sb(1)-Te(1) bond distances ranging from 2.96-3.45 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 2-coordinate geometry to three equivalent Sb(1) atoms. In the second Te site, Te(2) is bonded in a see-saw-like geometry to four equivalent Sb(1) atoms.
