Three complexes with the ditopic ligand 4Ј-[4-(quinolin-8yloxymethyl)phenyl]-2,2Ј:6Ј,2ЈЈ-terpyridine (abbreviated as L), [Ni(L) 2 ](CH 3 COO) 2 (1), [Cd(L) 2 ](ClO 4 ) 2 (2), and [Cu 2 (L) 2 ](ClO 4 ) 4 · 4DMF (3), were synthesized and characterized by elemental analysis, IR spectroscopy, and structurally analyzed by X-ray single-crystal diffraction. Interestingly, in complexes 1 and 2, two ligands adopt a tridentate chelating pattern where the oxaquinoline group is non-coordinated and coordinate with one M II ion (M = Ni for 1, M = Cd for 2) to form a mononuclear unit. In complex 3, two ligands bridge two Cu II 817 ions by pyridyl N atoms, ethereal O atoms, and quinolyl N atoms in a head-to-tail mode to generate a dinuclear [Cu 2 L 2 ] unit. Moreover, extended 1D and 2D supramolecular architectures are further constructed in 1-3 by multiple secondary interactions such as aromatic stacking and hydrogen bonding. Notably, the structural diversity of complexes 1-3 can be properly assigned to the central metal ions that have distinct coordination preferences. In addition, luminescent properties of the ligand and complex 2 were also investigated.
