Pb2Pd is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Pb2Pd cluster. Pd(1) is bonded in a distorted bent 120 degrees geometry to one Pb(1) and one Pb(2) atom. The Pd(1)-Pb(1) bond length is 1.11 Å. The Pd(1)-Pb(2) bond length is 1.91 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Pd(1) atom. In the second Pb site, Pb(2) is bonded in a distorted single-bond geometry to one Pd(1) atom.
