PdPb2Ge is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PdPb2Ge clusters. Pd(1) is bonded in a 1-coordinate geometry to one Pb(2) atom. The Pd(1)-Pb(2) bond length is 1.48 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted single-bond geometry to one Ge(1) atom. The Pb(1)-Ge(1) bond length is 2.18 Å. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to one Pd(1) and one Ge(1) atom. The Pb(2)-Ge(1) bond length is 1.71 Å. Ge(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Pb(2) atom.
