Solid state supramolecular assemblies of charged supermolecules (Na[2.2.2]cryptate)(+) and anionic carboranes with host cyclotriveratrylene

The complex {(Na[2.2.2]cryptate)[CTV][Co(C2B9H11)(2)]}(2)- (MeCN) (CTV = cyclotriveratrylene) features (Na[2.2.2]cryptate)(+)boolean AND CTV interplay as well as a closely packed chain of [Co(C2B9H11)(2)](-) counter-anions exhibiting dihydrogen bonding, and a similar cation-CTV assembly is found in (Na[2.2.2]cryptate)[CTV](CHCl3)(3)[CB11H12].
