La Tl Tl Sn
LaTl2Sn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaTl2Sn clusters. La(1) is bonded in a distorted single-bond geometry to one Tl(2) and one Sn(1) atom. The La(1)-Tl(2) bond length is 1.95 Å. The La(1)-Sn(1) bond length is 0.79 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a single-bond geometry to one Sn(1) atom. The Tl(1)-Sn(1) bond length is 1.17 Å. In the second Tl site, Tl(2) is bonded in a single-bond geometry to one La(1) atom. Sn(1) is bonded in a linear geometry to one La(1) and one Tl(1) atom.
