Complexes of type [Ru2 (L1/L2)(DMSO) 6Cl2](L1H2= 1-(2-Hydroxy-phenyl)-3-{4-[3-(2- hydroxy-phenyl)-3-oxo-propenyl]-phenyl}-propenone 1, L2H2= 1, 4-bis-(3-hydroxy-4-oxo-4H- chromen-2-yl)-benzene) 2, are prepared and characterized using spectroscopic techniques. In complex 1, both ruthenium centres possess a similar coordination environment in which all S-dmso coordinate to ruthenium centres. However, in complex 2, one ruthenium centre ...
