Abstract

2,2′:6′,2″:6″,2‴-Quaterpyridine (qtpy) forms double-helical binuclear complexes with metal ions adopting a pseudo-tetrahedral geometry; it is not necessary to design a sterically constrained ligand for this purpose, as the crystal structures of [Cu₂(qtpy)₂][PF₆]₂ and [Ag₂ (qtpy)₂][BF₄]₂ demonstrate; the role of the substituents is not to control the assembly of the helix, but to control its pitch.
