BeTc2Te crystallizes in the monoclinic Cm space group. Be(1) is bonded in a 3-coordinate geometry to one Tc(2) and four equivalent Te(1) atoms. The Be(1)-Tc(2) bond length is 2.87 Å. There are a spread of Be(1)-Te(1) bond distances ranging from 1.87-2.61 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Tc(2) and one Te(1) atom. The Tc(1)-Tc(2) bond length is 2.33 Å. The Tc(1)-Te(1) bond length is 1.88 Å. In the second Tc site, Tc(2) is bonded in a 2-coordinate geometry to one Be(1) and one Tc(1) atom. Te(1) is bonded in a 5-coordinate geometry to four equivalent Be(1) and one Tc(1) atom.
