Abstract

Abstract: 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.
