BeGa2Te is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeGa2Te clusters. Be(1) is bonded in a 3-coordinate geometry to two equivalent Ga(1) and one Te(1) atom. Both Be(1)-Ga(1) bond lengths are 0.88 Å. The Be(1)-Te(1) bond length is 0.65 Å. Ga(1) is bonded in a 3-coordinate geometry to one Be(1), one Ga(1), and one Te(1) atom. The Ga(1)-Ga(1) bond length is 0.65 Å. The Ga(1)-Te(1) bond length is 0.88 Å. Te(1) is bonded in a 3-coordinate geometry to one Be(1) and two equivalent Ga(1) atoms.
