摘要：

Adinuclear cobalt capsule [PF6 subset of(CH3CN)(2)(Co2L4)][PF6](3) (2), (L = bis-benzimidazole-1,3-phenylene) has been prepared using a self-assembly approach. This unique class of cage is perfectly designed to encapsulate weakly coordinated anions, i.e. BF4- and PF6- via an M center dot center dot center dot anion weak interaction as illustrated by X-ray and solid-state NMR investigations. Selective anion binding for BF4- over PF6- is also observed.
