Where there′s a wheel, there′s a way: The terpyridine-based title system has been synthesized through a facile self-assembly process. Two tris(terpyridine) ligands possessing angles of either 120° or 60° between adjacent tpy units were mixed with a stoichiometric amount of Zn2+ (2:6:12) to generate the desired coordination-driven bicycle-like wheel (90 % yield).
