Tc2PbSb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Tc2PbSb cluster. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Sb(1) atom. The Tc(1)-Pb(1) bond length is 1.88 Å. The Tc(1)-Sb(1) bond length is 1.83 Å. In the second Tc site, Tc(2) is bonded in a single-bond geometry to one Pb(1) atom. The Tc(2)-Pb(1) bond length is 1.88 Å. Pb(1) is bonded in a single-bond geometry to one Tc(1), one Tc(2), and one Sb(1) atom. The Pb(1)-Sb(1) bond length is 0.41 Å. Sb(1) is bonded in a single-bond geometry to one Tc(1) and one Pb(1) atom.
