We designed, synthesized, and characterized two types of dimeric forms of monocarba‐closo‐dodecaborate, namely, a “dumbbell”‐shaped dianion having a C−C bond and a “clackers”‐shaped monoanion having an iodonium linker. The unique architectures of these anionic molecules were established by X‐ray analysis. Spectroscopic analysis, DFT calculations, and reactivity experiments revealed high anionic and chemical stability of both anions, which are crucial properties for weakly coordinating anions.

Monocarba-closo-十二破坏的“哑铃”和“ clackers”形二聚衍生物

我们设计，合成，和其特征在于两种类型的二聚体形式monocarba-闭合碳-dodecaborate，即，具有C-C键并具有碘鎓接头一个“clackers”形单价阴离子“哑铃”形的二价阴离子。这些阴离子分子的独特结构是通过X射线分析建立的。光谱分析，DFT计算和反应性实验表明，两种阴离子均具有较高的阴离子和化学稳定性，这对于弱配位阴离子至关重要。
