LaTcHfTc is beta oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HfTc cluster and one LaTc cluster. In the HfTc cluster, Hf(1) is bonded in a single-bond geometry to one Tc(1) atom. The Hf(1)-Tc(1) bond length is 0.19 Å. Tc(1) is bonded in a single-bond geometry to one Hf(1) atom. In the LaTc cluster, La(1) is bonded in a single-bond geometry to one Tc(2) atom. The La(1)-Tc(2) bond length is 0.70 Å. Tc(2) is bonded in a single-bond geometry to one La(1) atom.
