Ge Bi Bi Te
GeBi2Te is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one GeBi2Te cluster. Ge(1) is bonded in a distorted single-bond geometry to one Te(1) atom. The Ge(1)-Te(1) bond length is 1.98 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted single-bond geometry to one Bi(2) atom. The Bi(1)-Bi(2) bond length is 0.93 Å. In the second Bi site, Bi(2) is bonded in a 2-coordinate geometry to one Bi(1) and one Te(1) atom. The Bi(2)-Te(1) bond length is 2.34 Å. Te(1) is bonded in an L-shaped geometry to one Ge(1) and one Bi(2) atom.
