Hg Pd Pb Pb
PdHgPb2 crystallizes in the triclinic P1 space group. Pd(1) is bonded in a distorted single-bond geometry to one Hg(1), one Pb(1), and two equivalent Pb(2) atoms. The Pd(1)-Hg(1) bond length is 3.12 Å. The Pd(1)-Pb(1) bond length is 1.40 Å. There is one shorter (2.64 Å) and one longer (3.49 Å) Pd(1)-Pb(2) bond length. Hg(1) is bonded in a distorted single-bond geometry to one Pd(1) and one Pb(2) atom. The Hg(1)-Pb(2) bond length is 3.55 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted single-bond geometry to one Pd(1) and two equivalent Pb(2) atoms. There is one shorter (2.55 Å) and one longer (2.58 Å) Pb(1)-Pb(2) bond length. In the second Pb site, Pb(2) is bonded in a 9-coordinate geometry to two equivalent Pd(1), one Hg(1), two equivalent Pb(1), and four equivalent Pb(2) atoms. There are two shorter (3.44 Å) and two longer (3.45 Å) Pb(2)-Pb(2) bond lengths.
