User:OrganoMetallurgy/Drafts/Cobalt bis(dicarbollide) anion

The Cobalt bis(1,2-dicarbollide) anion is a weakly coordinating anion It is the most studied dicarbollide complex.

Properties
Is amphiphilic, forms vesicles in water. Weakly coordinating High stability

Synthesis
Synthesis usually starts with degradation of o-carborane with base to form nido-[7,8-C2B9H11]- which is then deprotonated to form the 1,2-dicarbollide dianion, which reacts with cobalt chloride to produce the cobalt bis(1,2-dicarbollide) anion.

Reactions
Can be reversibly undergo two one electron reductions, and one one electron oxidation. Can be singly or doubly deprotonated by butyl lithium. Degraded to something something by alkali

Halogenation
Halogenated derivatives are far less reactive.
