Tc Pd Pd Pb
TcPd2Pb crystallizes in the triclinic P1 space group. Tc(1) is bonded in a distorted single-bond geometry to one Pd(1), two equivalent Pd(2), and one Pb(1) atom. The Tc(1)-Pd(1) bond length is 1.36 Å. There is one shorter (2.30 Å) and one longer (2.50 Å) Tc(1)-Pd(2) bond length. The Tc(1)-Pb(1) bond length is 3.18 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted single-bond geometry to one Tc(1) and three equivalent Pb(1) atoms. There are a spread of Pd(1)-Pb(1) bond distances ranging from 2.22-3.18 Å. In the second Pd site, Pd(2) is bonded in a 4-coordinate geometry to two equivalent Tc(1) and two equivalent Pb(1) atoms. There is one shorter (2.45 Å) and one longer (2.78 Å) Pd(2)-Pb(1) bond length. Pb(1) is bonded in a 8-coordinate geometry to one Tc(1), two equivalent Pd(2), three equivalent Pd(1), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 2.99 Å.
