Novel monoallenylidenes of Ru and Re, homobimetallic Ru/Ru and heterobimetallic Ru/Re complexes bridged by multiconjugated aromatic organic spacers such as bianthracenylidene and biphenylene were obtained and characterized by conventional spectroscopic techniques and elemental analysis. Electrochemical measurements coupled to spectroelectrochemistry and EPR spectroscopy proved that in the bis(allenylidene) complexes an electronic communication is present between either the two allenylidene bridges or the two metal centres, enticing extended intramolecular electronic mobility.

Abstract
Novel monoallenylidenes of Ru and Re, homobimetallic Ru/Ru and heterobimetallic Ru/Re complexes bridged by multiconjugated aromatic organic spacers such as bianthracenylidene and biphenylene were obtained and characterized by conventional spectroscopic techniques and elemental analysis. Electrochemical measurements coupled to spectroelectrochemistry and EPR spectroscopy proved that in the bis(allenylidene) complexes an electronic communication is present between either the two allenylidene bridges or the two metal centres, enticing extended intramolecular electronic mobility.File in questo prodotto:
