A tetranuclear iridium(iii) complex with a flavin analogue as a bridging ligand in different coordination modes and exchangeable anion encapsulation in a supramolecular cage

Abstract

A novel tetranuclear Ir(iii) complex involving unprecedented coordination modes of alloxazine formed a closed pi-space by intermolecular hydrogen bonding and the counter anions encapsulated in the space could be exchanged via self-assembly.
