Self‐Assembly of a Circular Double Helicate

Abstract

The simple reaction of a tris-bpy ligand strand with FeCl2 leads to the self-assembly of the unique cation 1, which consists of a torus formed by five ligands wrapped around five FeII ions in a double-helical fashion and closed around a central chloride ion. This structure, a fivefold circular helicate, is a helicate analogue of circular DNA.
