La2CoSn4 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 Co and ten Sn atoms. The La–Co bond length is 3.45 Å. There are eight shorter (3.34 Å) and two longer (3.50 Å) La–Sn bond lengths. In the second La site, La is bonded in a 4-coordinate geometry to four equivalent Co and ten Sn atoms. All La–Co bond lengths are 3.65 Å. There are a spread of La–Sn bond distances ranging from 3.39–3.67 Å. Co is bonded in a 5-coordinate geometry to five La and five Sn atoms. There are a spread of Co–Sn bond distances ranging from 2.49–2.55 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 1-coordinate geometry to six La, one Co, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.03 Å. In the second Sn site, Sn is bonded in a 4-coordinate geometry to six La and two equivalent Sn atoms. In the third Sn site, Sn is bonded in a 10-coordinate geometry to four La and two equivalent Co atoms. In the fourth Sn site, Sn is bonded in a 10-coordinate geometry to four La and two equivalent Co atoms.
