A new ligand bearing two tpy moieties and one bpy unit (tpy = 2,2':6',2 ''-terpyridine; bpy = 2,2'-bipyridine) linked by carbon-carbon single bonds and its corresponding trinuclear ruthenium complex were readily synthesized in high yield, and characterized by H-1 NMR spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESI/MS) and elemental analysis. The ruthenium complex exhibited moderate catalytic activity towards selective oxidation of alcohols in water with visible light under an air atmosphere. Investigations of UV/vis spectra, electrochemistry and ESI/MS suggested that the catalytic cycle involves two processes, Ru-c(II)-OH2/Ru-c(III)-OH and Ru-c(III)-OH/Ru-c(IV)=O. The effective electron transfer from the excited state *[Ru(tpy)(2)](2+) to [Co(NH3)(5)Cl]Cl-2 is proposed to be responsible for the good activities of this visible-light-driven system under an air atmosphere.
