La2FeSn4 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 11-coordinate geometry to one Fe and ten Sn atoms. The La–Fe bond length is 3.41 Å. There are a spread of La–Sn bond distances ranging from 3.37–3.56 Å. In the second La site, La is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of La–Sn bond distances ranging from 3.43–3.67 Å. Fe is bonded in a 5-coordinate geometry to one La and five Sn atoms. There are a spread of Fe–Sn bond distances ranging from 2.52–2.55 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to four La and two equivalent Fe atoms. In the second Sn site, Sn is bonded in a 2-coordinate geometry to four La and two equivalent Fe atoms. In the third Sn site, Sn is bonded in a 1-coordinate geometry to six La, one Fe, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.03 Å. In the fourth Sn site, Sn is bonded in a 8-coordinate geometry to six La and two equivalent Sn atoms.
