Abstract

The two mixed ligand complexes, cis-[Ru(mnt) (bpy) ₂] (1) and cis-[Ru (dmit) (bpy) ₂] (2) (where mnt ^2- is maleonitriledithiolate and dmit ^2- reprents 4, 5-dimercapto-1, 3-dithiole-2-thione), have been synthesized and characterized by element analysis and IR spectra. The electronic spectra of 1 and 2 in DMF solutions showed that the two complexes have broad absorption charge transfer bands [LMCT i.e. charge transfer from dithiolate to Ru (II) or LL′CT, that is, charge transfer from dithiolate to 2, 2′-bipyridine] in the visible region. Compared with 1, the LMCT or LL′CT band for 2 shifts to low frequency. The results of electrochemistry of the two complexes in DMF are consistent with that of the electronic spectra.
