We describe a study of the equilibrium binding of Zn2+ to binary mixtures of tridentate ligands terpyridine (1), 2,5-(CHNC6H5)2pyridine (2) and (2-pyridyl)NHNCH(2-pyridyl) (3) which leads to the formation of a dynamic mixture of homo ([Zn(1)2](CF3SO3)2 4, [Zn(2)2](CF3SO3)2 5, [Zn(3)2](CF3SO3)2 6) and hetero ([Zn(1)(3)](CF3SO3)2 7, [Zn(1)(2)](CF3SO3)2 8, [Zn(2)(3)](CF3SO3)2 9) coordination compounds We report the crystal structures of five such complexes (4, 5, 7–9) which assemble into complementary duplex compounds that further self-organize into double helical- or lamellar-type architectures in the solid state. The ligand exchange between homo-duplex complexes in solution leads to the preferential formation of the heteroduplex complexes. As might be expected these processes display a statistical distribution of homo-duplex:heteroduplex:homo-duplex complexes of 1:2:1 for the mixtures resulting from 4:6 and 5:6 ligands. However, complex 8 is preferred in a 4:5 mixture which presents a composition of 1:4:1 (amplification factor of about 33%). The X-ray structural determinations of selected single crystals resulting from the stoichiometric mixtures of homo-duplex complexes show unique heteroduplex superstructures 7–9 in the solid state. The present results present the solid-state structures of homo- and hetero-complexes resulting from terpyridine-type ligands 1–3 and Zn2+ metal ions. The heteroduplex Zn2+ complexes 7–9 are quant. crystallized in the solid state by statistical (7, 9) and structural (8) driven selection in solution from a binary mixture of the terpyridine-type complexes and then trapped by crystallization in the solid state.
