Summary:Self control! A potentially dianionic helicand ligand is used to exert control over the assembly of metal complexes into common helical structures or supramolecular clusters depending on the oxidation state of the metal (see scheme). In the tetranuclear cluster dihelicates, a polyhedron of metal ions is the helical axis. The metal cluster in these complexes is stabilized by two soft donor atoms in the ligand.
