LaTc2Te crystallizes in the monoclinic Cm space group. La(1) is bonded in a 1-coordinate geometry to one Tc(1) and one Tc(2) atom. The La(1)-Tc(1) bond length is 2.40 Å. The La(1)-Tc(2) bond length is 3.26 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 1-coordinate geometry to one La(1) and one Te(1) atom. The Tc(1)-Te(1) bond length is 1.07 Å. In the second Tc site, Tc(2) is bonded in a 4-coordinate geometry to one La(1) and three equivalent Te(1) atoms. There is one shorter (2.51 Å) and two longer (3.03 Å) Tc(2)-Te(1) bond lengths. Te(1) is bonded in a distorted single-bond geometry to one Tc(1) and three equivalent Tc(2) atoms.
