Zn2PbBi is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Zn2PbBi cluster. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a bent 150 degrees geometry to one Zn(2) and one Pb(1) atom. The Zn(1)-Zn(2) bond length is 1.82 Å. The Zn(1)-Pb(1) bond length is 2.41 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one Zn(1) atom. Pb(1) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one Bi(1) atom. The Pb(1)-Bi(1) bond length is 1.28 Å. Bi(1) is bonded in a single-bond geometry to one Pb(1) atom.
