Ta Ta Bi Te
Ta2BiTe is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2BiTe cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a distorted single-bond geometry to one Te(1) atom. The Ta(1)-Te(1) bond length is 1.53 Å. In the second Ta site, Ta(2) is bonded in a single-bond geometry to one Te(1) atom. The Ta(2)-Te(1) bond length is 1.05 Å. Bi(1) is bonded in a single-bond geometry to one Te(1) atom. The Bi(1)-Te(1) bond length is 1.05 Å. Te(1) is bonded in a 3-coordinate geometry to one Ta(1), one Ta(2), and one Bi(1) atom.
