In2Te3 crystallizes in the tetragonal I4mm space group. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Te(3) atoms to form edge-sharing InTe4 tetrahedra. In the second In site, In(2) is bonded in a 3-coordinate geometry to one Te(1), one Te(3), and two equivalent Te(2) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent In(2) and four equivalent Te(2) atoms. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to two equivalent In(2) and one Te(1) atom. In the third Te site, Te(3) is bonded in a T-shaped geometry to one In(2) and two equivalent In(1) atoms.
In2Te3 crystallizes in the tetragonal I4mm space group. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Te(3) atoms to form edge-sharing InTe4 tetrahedra. There are two shorter (2.83 Å) and two longer (2.94 Å) In(1)-Te(3) bond lengths. In the second In site, In(2) is bonded in a 3-coordinate geometry to one Te(1), one Te(3), and two equivalent Te(2) atoms. The In(2)-Te(1) bond length is 3.40 Å. The In(2)-Te(3) bond length is 2.90 Å. Both In(2)-Te(2) bond lengths are 2.90 Å. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent In(2) and four equivalent Te(2) atoms. All Te(1)-Te(2) bond lengths are 3.11 Å. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to two equivalent In(2) and one Te(1) atom. In the third Te site, Te(3) is bonded in a T-shaped geometry to one In(2) and two equivalent In(1) atoms.
