Be Si Te Te
BeSiTe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeSiTe2 cluster. Be(1) is bonded in a 1-coordinate geometry to one Si(1) and one Te(1) atom. The Be(1)-Si(1) bond length is 1.55 Å. The Be(1)-Te(1) bond length is 0.30 Å. Si(1) is bonded in a distorted water-like geometry to one Be(1) and one Te(2) atom. The Si(1)-Te(2) bond length is 0.78 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a single-bond geometry to one Be(1) atom. In the second Te site, Te(2) is bonded in a single-bond geometry to one Si(1) atom.
