Fe2IrPb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Fe2IrPb cluster. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted bent 150 degrees geometry to one Fe(2) and one Ir(1) atom. The Fe(1)-Fe(2) bond length is 0.94 Å. The Fe(1)-Ir(1) bond length is 1.13 Å. In the second Fe site, Fe(2) is bonded in a distorted water-like geometry to one Fe(1) and one Pb(1) atom. The Fe(2)-Pb(1) bond length is 2.07 Å. Ir(1) is bonded in a single-bond geometry to one Fe(1) atom. Pb(1) is bonded in a distorted single-bond geometry to one Fe(2) atom.
