La2Sn5 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first 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 3.30–3.60 Å. In the second La site, La is bonded to twelve Sn atoms to form a mixture of face and corner-sharing LaSn12 cuboctahedra. There are a spread of La–Sn bond distances ranging from 3.34–3.45 Å. There are six inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to six equivalent La and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.12 Å. In the second Sn site, Sn is bonded in a distorted square co-planar geometry to four La and four equivalent Sn atoms. All Sn–Sn bond lengths are 3.34 Å. In the third Sn site, Sn is bonded in a distorted rectangular see-saw-like geometry to four La and six Sn atoms. Both Sn–Sn bond lengths are 3.33 Å. In the fourth Sn site, Sn is bonded in a distorted rectangular see-saw-like geometry to four equivalent La and two equivalent Sn atoms. In the fifth Sn site, Sn is bonded in a distorted square co-planar geometry to four equivalent La atoms. In the sixth Sn site, Sn is bonded in a distorted square co-planar geometry to four equivalent La atoms.
