摘要：

The reaction of [Ru(tpy)Cl-3] with the potentially cyclometallating ligand 2,2':6',4 ''-terpyridine (HL) results in the formation of the non-metallated complex ion [Ru(tpy)(HL)Cl](+) and the complex ion [Ru(tpy)(LH)](2+) in which the cyclometallated ligand L is protonated on the non-coordinated nitrogen atom. If ethane-1,2-diol is used as the solvent the latter complex is the major product, while the use of glacial acetic acid favours the former. This electron-withdrawing pyridinium functionality significantly affects the properties of the complex. In contrast, the non-metallated complex behaves like similar ruthenium complexes with N5Cl donor sets. Both complexes have been fully characterized as their hexafluorophosphate salts, and studied by cyclic voltammetry and electronic spectroscopy. The complex [Ru(tpy)(LH)][PF6](2) is weakly luminescent at room temperature in acetonitrile solution.
