Electrochemical behavior of mono- and bimetallic chromiumtricarbonyl and cationic manganesetricarbonyl of fluxional dibenzo[a,e]cyclooctatetraene (DBCOT) complexes were studied via cyclic voltammetry over a range of scan rates (20 – 2000 mV/s) and temperatures (0 °C and 25 °C). The presented work displays electrochemical reduction mechanisms associated with eight-membered ring coordinated M(CO)3 systems that undergo rapid ring inversion in solution. The electrochemical studies of these complex systems exhibit comparitively similar behaviors, which suggest relatively undifferentiated mechanisms. Slight differences between the chromium and isoelectronic cationic manganese are seen in their chemical reactions in solution and the potential at which they reduce. The significance of the electrochemical studies of these complexes are justified by their potential contribution to nanotechnology considering the possibility of generating a cylindrical nanostructure containing the tub-shaped eight-membered ring ð-coordinated M(CO)3 system. The high probability of a haptotropic shift to the eight-membered ring upon reduction could prove to be beneficial to electrocatalysis.
