The isolation of a mononuclear key intermediate and the measurement of stability constants gave insight into the stepwise formation of helicates (depicted on the right) consisting of copper( I ) ions and oligopyridine ligands. A positive cooperativity for cation binding is not mandatory for helicate formation.
