TcPtPb2 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a 3-coordinate geometry to one Pt(1), one Pb(1), and two equivalent Pb(2) atoms. The Tc(1)-Pt(1) bond length is 1.38 Å. The Tc(1)-Pb(1) bond length is 2.21 Å. There is one shorter (2.34 Å) and one longer (3.22 Å) Tc(1)-Pb(2) bond length. Pt(1) is bonded in a distorted single-bond geometry to one Tc(1) and two equivalent Pb(2) atoms. There is one shorter (2.21 Å) and one longer (3.13 Å) Pt(1)-Pb(2) bond length. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 1-coordinate geometry to one Tc(1) and two equivalent Pb(2) atoms. There is one shorter (2.21 Å) and one longer (2.63 Å) Pb(1)-Pb(2) bond length. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to two equivalent Tc(1), two equivalent Pt(1), and two equivalent Pb(1) atoms.
