摘要：

Monomethylation of 2,2':6',2 ''-terpyridine (terpy) afforded the N-methyl-2,2':6':2 ''-terpyridinium cation, [Hmterpy](+). With one of the terminal pyridine ring nitrogen atoms thus protected;it co-ordinates to ruthenium(II) either as a didentate N,N'-donor giving [Ru(terpy)(Hmterpy-N,N')Cl][PF6](2), or as a cyclometallating terdentate ligand giving [Ru(terpy)(mterpy-N,N',C)][PF6](2), depending upon the reaction conditions. Both complexes have been fully characterised by spectroscopic and electrochemical methods, and the crystal structures of [Ru(terpy)(mterpy-N,N',C)][BF4](2) . 2MeCN and [Ru(terpy)(Hmterpy-N,N')Cl][PF6](2) . 2MeCN determined.
