TlI[C(SiMe3)3]—An Alkylthallium(I) Compound with a Distorted Tetrahedron of Tl Atoms in the Solid State

Abstract
Weak thallium–thallium interactions are present in the thallium tetrahedron of the crystalline alkylthallium(I) compound Tl[C(SiMe3)3], which is easily accessible from cyclopentadienylthallium(I) and tris(trimethylsilyl)methyllithium. In solution, however, only the monomer of the extremely thermally sensitive compound can be detected.
