摘要三[（1-异丙基苯并咪唑-2-基）二甲基硅基]甲基配体[Tism Pr i Benz]通过[Tism Pr i Benz] Li与TlOAc反应，得到了六周期元素的碳烷配合物[Tism Pr i Benz] Tl。[Tism Pr i Benz] Tl可作为合成其他[Tism Pr i Benz] MX配合物的试剂，包括镉甲基化合物[Tism Pr i Benz] CdMe。通过x射线衍射测定了[Tism Pr i Benz] CdMe的分子结构，表明它具有一个平面基序，与锌的同系物[κ 3-Tism Pr i Benz] ZnMe的κ 3配位相反。此外，[Tism Pr i Benz] CdMe的结构也不同于其他[Tism Pr i Benz] CdX化合物，因为[Tism Pr i Benz] CdMe的Cd-C键明显短于其他衍生物，而Cd-N键的长度则相当长。
Abstract The tris [(1-isopropylbenzimidazol-2-yl) dimethylsilyl] methyl ligand,[Tism Pr i Benz], has been used to afford a carbatrane complex of an element of the sixth period, namely [Tism Pr i Benz] Tl, via the reaction of [Tism Pr i Benz] Li with TlOAc.[Tism Pr i Benz] Tl may be employed as a reagent for the synthesis of other [Tism Pr i Benz] MX complexes, including the cadmium methyl compound,[Tism Pr i Benz] CdMe. The molecular structure of [Tism Pr i Benz] CdMe has been determined by X-ray diffraction, which indicates that it possesses an atrane motif, in contrast to the κ 3-coordination observed for the zinc congener,[κ 3-Tism Pr i Benz] ZnMe. Furthermore, the structure of [Tism Pr i Benz] CdMe is also different to other [Tism Pr i Benz] CdX compounds because the Cd–C atrane bond of [Tism Pr i Benz] CdMe is distinctly shorter than in other derivatives, while the Cd–N bond lengths are considerably longer.
