Te Te Te As
AsTe3 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AsTe3 cluster. As(1) is bonded in a distorted bent 120 degrees geometry to one Te(1) and one Te(3) atom. The As(1)-Te(1) bond length is 0.83 Å. The As(1)-Te(3) bond length is 1.24 Å. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted bent 120 degrees geometry to one As(1) and one Te(2) atom. The Te(1)-Te(2) bond length is 0.89 Å. In the second Te site, Te(2) is bonded in a single-bond geometry to one Te(1) atom. In the third Te site, Te(3) is bonded in a single-bond geometry to one As(1) atom.
