SrLaSn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrLaSn2 cluster. Sr(1) is bonded in a 2-coordinate geometry to one La(1) and one Sn(2) atom. The Sr(1)-La(1) bond length is 1.75 Å. The Sr(1)-Sn(2) bond length is 1.57 Å. La(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sn(1), and one Sn(2) atom. The La(1)-Sn(1) bond length is 2.12 Å. The La(1)-Sn(2) bond length is 2.12 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one La(1) atom. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Sr(1) and one La(1) atom.
