Hf2TcTe crystallizes in the monoclinic Pm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 1-coordinate geometry to one Hf(2), two equivalent Tc(1), and two equivalent Te(1) atoms. The Hf(1)-Hf(2) bond length is 0.44 Å. There is one shorter (3.57 Å) and one longer (3.98 Å) Hf(1)-Tc(1) bond length. There is one shorter (1.26 Å) and one longer (2.17 Å) Hf(1)-Te(1) bond length. In the second Hf site, Hf(2) is bonded in a 1-coordinate geometry to one Hf(1), two equivalent Tc(1), and two equivalent Te(1) atoms. There is one shorter (3.46 Å) and one longer (3.89 Å) Hf(2)-Tc(1) bond length. There is one shorter (1.26 Å) and one longer (2.17 Å) Hf(2)-Te(1) bond length. Tc(1) is bonded in a 10-coordinate geometry to two equivalent Hf(1), two equivalent Hf(2), four equivalent Tc(1), and two equivalent Te(1) atoms. All Tc(1)-Tc(1) bond lengths are 3.39 Å. There is one shorter (3.45 Å) and one longer (3.57 Å) Tc(1)-Te(1) bond length. Te(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Hf(1), two equivalent Hf(2), and two equivalent Tc(1) atoms.
