Coordination-driven self-assembly of M10L8 metal–organic bi-capped square antiprisms with adaptable cavities†
Abstract
A family of polyhedral metal-imidazolate cages based on the flexible bi-imidazole ligand L and Cu2+ ions have been synthesized and characterized, featuring an unusual Cu10L8 bicapped square antiprism structure (or Johnson solids, J17) with an adaptable cavity. These metal–organic cages encapsulate anions, and they will expand or compress after they are filled with different-sized anions.
