Electronic communication in binuclear Cr(0)-aminocarbenes: an electrochemical study

Popis výsledku v původním jazyce

Fischer type carbene complexes with the general formula (CO)5Cr=C(NMe2)(R) have characteristic charge distribution: an electron rich central metal atom and an electron deficient carbene carbon atom. They behave as molecules with two redox centres: Eox depends on the metal nature whereas Ered reflects the carbene ligand constitution. This work deals with electrochemical behaviour of binuclear Cr(0) complexes possessing either m-Ph or 2,2?-dithiophenyl bridge. In comparison with their mononuclear analogues we have been able to determine the extent of the electronic communication between their metal centres which is important for possible application of analogous molecules as molecular devices. m-Ph bridge blocks the electronic communication between the Cr atoms, as Eox remains very similar to that of the mononuclear complex but the current is twofold. Delocalized ?-electron system of the 2,2?-dithiophene bridge allows some electronic communication between metal centres during oxidation b
