Hf Be Be Te
Be2HfTe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2HfTe cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Te(1) atom. The Be(1)-Te(1) bond length is 0.34 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Hf(1) atom. The Be(2)-Hf(1) bond length is 0.44 Å. Hf(1) is bonded in a bent 120 degrees geometry to one Be(2) and one Te(1) atom. The Hf(1)-Te(1) bond length is 1.31 Å. Te(1) is bonded in a distorted water-like geometry to one Be(1) and one Hf(1) atom.
