Symmetric and asymmetric bimetallic ruthenium (II) complexes have been synthesized and characterized. The asymmetric complexes are of the form [(TL)2Ru(BL)Ru(Cl)(tpy)]3+, where TL is the bidentate ligand 1,10-phenanthroline (phen) or 2,2’-bipyridine (bpy), tpy is the tridentate ligand 2,2’:6’,2”-terpyridine and BL is a bridging ligand 2,3-bis(2-pyridyl)pyrazine (dpp) or 2,2’bipyrimidine (bpm). The symmetric complexes are of the form {[(TL)2Ru]2(BL)}4+ and {[(tpy)(Cl)Ru]2(BL)}2+. Changing the TL ligand on the complexes should affect the light absorbing properties of the complexes and thus affect the photodynamic ability of the complexes.
