The asymmetric bimetallic ruthenium (II) complexes with the general form of [(bpy)₂Ru(BL)RuCl(tpy)]³⁺ (bpy = 2,2'-bipyridine, tpy = 2,2':6',2�-terpyridine) were synthesized by a building block approach. The bridging ligand (BL), dpp= 2,3-bis(2-pyridyl)pyrazine or bpm= 2,2'-bipyrimidine, controls the distance between the metal centers. The complexes are being studied with respect to their electrochemistry and their electronic absorption and emission spectroscopy. The characterization techniques, mentioned above, were employed in order to determine how the bridging ligand will affect the level of communication between the metal centers.
