Electronic interactions in diyne Co2(CO)6 complexes

Electrochemical criteria are used to evaluate the electronic interaction between redox centres in the π-conjugated diyne complexes (RCSC[Co₂(CO)₆]C=EC[Co₂(CO)₆]R] and (RC=C[Co₂(CO)₆]-(S)-C=C[Co₂(CO)₆]R] (R = Ph,Fc) where the aromatic spacer S is phenyl, napthalene or anthracene. Voltammetry at microelectrode, differential pulse techniques and low temperature measurements are used to obviate the chemical complications following the primary redox process. A mechanism is proposed which successfully simulates the electrochemical data.
