Both binuclear complexes utilize 4,4’-bipyridine bridging ligands to form straight lines Structure, linear PPh3 or CH3 CN ends for the end group.Au (Ⅰ) 2 coordination, Cu (Ⅰ) coordination 4. Both complexes have photoluminescence properties, in which the complex 1 luminescence from MLCT excited state, while the complex 2 is ligand-affected ligand internal luminescence.
