FeAg2Pb crystallizes in the triclinic P1 space group. Fe(1) is bonded in a single-bond geometry to one Ag(1), one Ag(2), and one Pb(1) atom. The Fe(1)-Ag(1) bond length is 2.45 Å. The Fe(1)-Ag(2) bond length is 2.76 Å. The Fe(1)-Pb(1) bond length is 1.36 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Fe(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 2.15 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to one Fe(1), one Ag(1), and two equivalent Pb(1) atoms. There is one shorter (2.24 Å) and one longer (2.38 Å) Ag(2)-Pb(1) bond length. Pb(1) is bonded in a distorted single-bond geometry to one Fe(1) and two equivalent Ag(2) atoms.
