Summary

The formation of copper(II) ternary complexes [Cu(tpy)(L)]∘ (tpy = 2,2′,2″-terpyridine; L = oxydiacetate, thiodiacetate, iminodiacetate or dipicolinate) has been studied by potentiometric measurements in aqueous solution at 25° and I = 0.1 mol dm−3 (NaNO3 or NaClO4). All the systems investigated also form protonated species of the [Cu(tpy)(L)H]+ type. The effect of the different heteroatoms (donor atoms) in the ligands L (i.e. O, S or N), other than oxygens of the carboxylic groups, on the stability of the mixed complexes has been evaluated and compared with the trends observed for the analogous complexes of copper(II) with 2,2′-bipyridine (bpy).

The stabilization of ternary complexes of copper(II) with respect to the different coordination levels is also discussed.
