Tc Tc Ag Pb
Tc2AgPb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Tc2AgPb cluster. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Ag(1) atom. The Tc(1)-Ag(1) bond length is 1.27 Å. In the second Tc site, Tc(2) is bonded in a distorted L-shaped geometry to one Ag(1) and one Pb(1) atom. The Tc(2)-Ag(1) bond length is 0.59 Å. The Tc(2)-Pb(1) bond length is 1.00 Å. Ag(1) is bonded in a 3-coordinate geometry to one Tc(1), one Tc(2), and one Pb(1) atom. The Ag(1)-Pb(1) bond length is 1.11 Å. Pb(1) is bonded in a 2-coordinate geometry to one Tc(2) and one Ag(1) atom.
