摘要: Abstract The reaction of [Ru(tpy)Cl 3 ] with the potentially cyclometallating ligand 6-phenyl-2,2′-bipyridine (HL) has been examined in a variety solvents. In glacial acetic acid acts as substituted 2,2′-bipyridine and reacts to give complex cation [Ru(tpy)(HL)CL] + , containing bidentate N,N′-bonded HL ligand. structure this unambiguously established from its 1 H NMR spectrum. contrast, use water solvent gives cyclometallated [Ru(tpy)(L)] . methanol butan-1-ol, mixtures these two products are formed. work extended 2,2′:6′,2″-terpyridines aromatic substituents 4′ position complexes have characterised by NMR, electronic FAB mass spectroscopic techniques also cyclic voltammetry.
