FeIn2Sn crystallizes in the triclinic P1 space group. Fe(1) is bonded in a single-bond geometry to two equivalent In(2) and one Sn(1) atom. There is one shorter (2.74 Å) and one longer (3.28 Å) Fe(1)-In(2) bond length. The Fe(1)-Sn(1) bond length is 0.10 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 6-coordinate geometry to two equivalent In(1), two equivalent In(2), and two equivalent Sn(1) atoms. Both In(1)-In(1) bond lengths are 3.30 Å. There is one shorter (2.65 Å) and one longer (2.76 Å) In(1)-In(2) bond length. There is one shorter (2.74 Å) and one longer (3.28 Å) In(1)-Sn(1) bond length. In the second In site, In(2) is bonded in a 6-coordinate geometry to two equivalent Fe(1), two equivalent In(1), and two equivalent In(2) atoms. Both In(2)-In(2) bond lengths are 3.30 Å. Sn(1) is bonded in a single-bond geometry to one Fe(1) and two equivalent In(1) atoms.
