摘要：

A bent thallocene anion is found in complexes 1 and 2, which are prepared by the reaction of [CpTl] and [Cp2Mg] (for 1) or [CpLi] (for 2) and N,N,N′,N′,N″‐pentamethyldiethylenediamine (PMDETA). The [(η5‐Cp)2Tl]− anion is isoelectronic and isostructural with stannocene. Ab initio calculations show that the bent structure with CS symmetry is only marginally more stable than the linear conformer with D5h symmetry. (Formula Presented.)
