Sterically controlled self-assembly of tetrahedral M6L4 cages via cationic N-donor ligands†
Abstract
Tripodal cationic N-donor ligands exhibit sterically controlled self-assembly of tetrahedral M6L4 coordination cages that promote selective anion encapsulation (PF6− > OTf−) in the solid state. The described method is a potential template for stepwise assembly of hetero-ligand coordination cages and polymers.
