Fe2ZnPb is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Fe2ZnPb clusters. Fe(1) is bonded in a 3-coordinate geometry to one Fe(1), one Zn(1), and one Pb(1) atom. The Fe(1)-Fe(1) bond length is 0.12 Å. The Fe(1)-Zn(1) bond length is 0.17 Å. The Fe(1)-Pb(1) bond length is 0.17 Å. Zn(1) is bonded in a distorted single-bond geometry to two equivalent Fe(1) and one Pb(1) atom. The Zn(1)-Pb(1) bond length is 0.12 Å. Pb(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one Zn(1) atom.
