N2 - A facile synthetic procedure has been used to prepare one five-coordinate and four six-coordinate copper(II) complexes of 4′-chloro-2,2′:6′,2″-terpyridine (tpyCl) ligand with different counterions (SO42 -, NO3-, BF4-, PF6-, and ClO4-) in high yields. They are formulated as [Cu(tpyCl-κ3N,N′,N′′)(SO4-κO)(H2O-κO)] · 2H2O (1), trans-[Cu(tpyCl-κ3N,N′,N″)(NO3-κO)2(H2O-κO)] (2), [Cu(tpyCl-κ3N,N′,N″)2](BF4)2 (3), [Cu(tpyCl-κ3N,N′,N″)2](PF6)2 (4) and [Cu(tpyCl-κ3N,N′,N″)2](ClO4)2 (5) and versatile interactions in supramolecular level including coordinative bonding, O-H⋯O, O-H⋯Cl, C-H⋯F, and C-H⋯Cl hydrogen bonding, π-π stacking play essential roles in forming different frameworks of 1-5. It is concluded that the difference of coordination abilities of the counterions used and the experimental conditions codominate the resulting complexes with 1:1 or 1:2 ratio of metal and ligand.
