The next homologue of the bis(cyclopentadienyl)thallate anion; synthesis and X-ray structure determination of [(η5-C5H 5)Tl(μ-C5H5)Tl(μ5-C 5H5)]-[Li(12-crown-4)2] +·thf

Reaction of (C5H5)Li with (η5-C 5H5)Tl (1.2 equiv.) in the presence of 12-crown-4 (2 equiv.) produces the ion-separated complex [(η5-C 5H5)Tl(μ-C5H5) Tl(μ5-C5H5)]-[Li(12-crown-4) 2]+·thf 1 which contains the first homometallic main group metal triple-decker sandwich as the anion; this anion can be viewed as the first homologue of the thallocene anion [(η5-C 5H5)2Tl]- and is a molecular segment of the polymeric structure of [(η5-C5H 5)Tl].
