AuAg2Pb crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one AuAg2Pb cluster. Au(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Au(1)-Pb(1) bond length is 1.61 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ag(2) atom. The Ag(1)-Ag(2) bond length is 2.29 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Ag(1) and one Pb(1) atom. The Ag(2)-Pb(1) bond length is 0.81 Å. Pb(1) is bonded in a 2-coordinate geometry to one Au(1) and one Ag(2) atom.
