Abstract

A dinuclear cobalt capsule [PF6⊂(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⋯anion weak interaction as illustrated by X-ray and solid-state NMR investigations. Selective anion binding for BF4− over PF6− is also observed.
