Synthesis and Characterization of the Asymmetric Bimetallic Complexes[(tpy)RuCl(dpp)Ru(bpy)2]3+ and [(tpy)RuCl(bpm)Ru(bpy)2]3+

Rustam Vachhani and Matthew T. Mongelli. Kean University, Union, NJ

Asymmetric bimetallic ruthenium (II) complexes of the form [(tpy)RuCl(BL)Ru(bpy)2]3+, where tpy = 2,2':6',2�-terpyridine, bpy = 2,2'-bipyridine, and BL = the bridging ligand dpp (2,3-bis(2-pyridyl)pyrazine) or bpm (2,2'-bypyrimidine), have been synthesized. These complexes show low energy visible MLCT electronic absorbance and well separated oxidation potentials due to the metals being in different ligand environments. The synthesis, purification and characterization of these complexes will be presented.
