摘要：

The reaction of [Ru(tpy)Cl3] with the potentially cyclometallating ligand 6-phenyl-2,2'-bipyridine (HL) has been examined in a variety of solvents. In glacial acetic acid the ligand acts as a substituted 2,2'-bipyridine and reacts to give the complex cation [Ru(tpy)(HL)Cl]+, containing a bidentate N,N'-bonded HL ligand. The structure of this complex has been unambiguously established from its H-1 NMR spectrum. In contrast, the use of water as a solvent gives the cyclometallated complex cation [Ru(tpy)(L)]+. In methanol and butan-1-ol, mixtures of these two products are formed. The work has been extended to 2,2':6',2''-terpyridines with aromatic substituents in the 4' position and the complexes have been characterised by H-1 NMR, electronic and FAB mass spectroscopic techniques and also by cyclic voltammetry.
