La Tl V V
LaV2Tl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaV2Tl clusters. La(1) is bonded in a single-bond geometry to one V(1) atom. The La(1)-V(1) bond length is 2.22 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to one La(1) and one V(2) atom. The V(1)-V(2) bond length is 1.70 Å. In the second V site, V(2) is bonded in a single-bond geometry to one V(1) and one Tl(1) atom. The V(2)-Tl(1) bond length is 0.43 Å. Tl(1) is bonded in a single-bond geometry to one V(2) atom.
