BeLa2Te crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeLa2Te cluster. Be(1) is bonded in a distorted single-bond geometry to one La(2) atom. The Be(1)-La(2) bond length is 2.54 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to one La(2) and one Te(1) atom. The La(1)-La(2) bond length is 1.26 Å. The La(1)-Te(1) bond length is 1.59 Å. In the second La site, La(2) is bonded in a distorted single-bond geometry to one Be(1), one La(1), and one Te(1) atom. The La(2)-Te(1) bond length is 1.26 Å. Te(1) is bonded in a 1-coordinate geometry to one La(1) and one La(2) atom.
