FeIn2Pb crystallizes in the triclinic P1 space group. Fe(1) is bonded in a 1-coordinate geometry to one In(2) and two equivalent In(1) atoms. The Fe(1)-In(2) bond length is 1.77 Å. There is one shorter (2.30 Å) and one longer (3.26 Å) Fe(1)-In(1) bond length. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to two equivalent Fe(1), two equivalent In(1), and one Pb(1) atom. Both In(1)-In(1) bond lengths are 3.05 Å. The In(1)-Pb(1) bond length is 3.41 Å. In the second In site, In(2) is bonded in a 3-coordinate geometry to one Fe(1) and two equivalent Pb(1) atoms. There is one shorter (1.84 Å) and one longer (2.83 Å) In(2)-Pb(1) bond length. Pb(1) is bonded in a distorted single-bond geometry to one In(1) and two equivalent In(2) atoms.
