The recent emergence of applications of carboranes as materials for nanotechnology and pharmacophores in drug design has greatly expanded the potential use of boron clusters. The cobaltabisdicarbollide anion [3,3-Co(1,2-C2B9H11)2] is a sandwich complex characterized by an extraordinary chemical and thermal stability. The cobaltabisdicarbollide is a hydrophobic and weakly nucleophilic anion. Recently, Teixidor and co-workers reported that this cosane presented an amphiphilic character that led to the formation of monolayer vesicles at low concentration in water and small micelles at higher concentrations. All these properties make it suitable for the stabilization of transient complex cation particles in catalysis and for use as a strong non-oxidizing acid or as a solid electrolyte.
