摘要：
The cyclometalated complexes [RuL(terpy)] [PF6](2) (3, L = N"-methyl-4'-methylthio-2,2': 6',4"-terpyridinium; 4, L = N"-methyl-4'-methylthio-2,2':6',3"-terpyridinium) with a (N,N,N)(N,N,C)-coordination mode were synthesized in good yields and fully characterized by X-ray crystallographic, spectroscopic, and electrochemical measurements. C-13{H-1} NMR and electronic spectra revealed that the Ru-C bond of complex 4, which has a quaternized N-Me unit at the pares-position of the carbon atom bonding to the metal center in the terminal ring of the tridentate ligand, involves carbenic (Ru=C) character in solution.
