7-bis(2′-[1′,10′]phenanthrolinyl)pyrenes. These ligands, along with the tetrahydro analogue to the 2,7-pyrene-bridged isomer, have been treated with [Ru([D8]bpy)2Cl2], where [D8]bpy = [D8]2,2′-bipyridine, to afford the dinuclear RuII complexes, 1H NMR and X-ray crystallographic analysis of which indicate that the bridging pyrene is layered between a [D8]bpy auxiliary ligand coordinated to each metal atom.
