Pb Pb Au Cl
PbAuPbCl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one 7439-92-1 atom and one AuPbCl cluster. In the AuPbCl cluster, Au(1) is bonded in a distorted single-bond geometry to one Pb(2) and one Cl(1) atom. The Au(1)-Pb(2) bond length is 1.55 Å. The Au(1)-Cl(1) bond length is 0.74 Å. Pb(2) is bonded in a 2-coordinate geometry to one Au(1) and one Cl(1) atom. The Pb(2)-Cl(1) bond length is 1.75 Å. Cl(1) is bonded in a single-bond geometry to one Au(1) and one Pb(2) atom.
