Head-To-Tail and Heteroleptic Pentanuclear Circular Helicates

By Kirsty E. Allen, Robert A. Faulkner, Lindsay P. Harding, Craig R. Rice, Thomas Riis-Johannessen, Melanie L. Voss and Martina Whitehead


Everybody form a circle: Careful design of ligand strands and their reaction with Cu2+ ions leads to the formation of the title helicates. Incorporation of differing numbers of N-donor units within a ligand strand containing a phenyl spacer results in a pentanuclear head-to-tail circular helicate, whereas reaction of two different ligands results in a heteroleptic pentanuclear circular helicate (see picture; green: Cu, red and blue: ligands)
