W. Bruns et al., SPECTROELECTROCHEMICAL CHARACTERIZATION OF A PYRAZINE-BRIDGED MIXED-VALENT (4D5 4D6) ORGANOMETALLIC ANALOG OF THE CREUTZ-TAUBE ION/, Journal of the Chemical Society, Chemical Communications, (24), 1993, pp. 1868-1869
The dinuclear complex ion transmer-[(PPri3)2(CO)3Mo(mu-PZ)MO(CO)3(PPri
3)2]+ (pz = pyrazine), the closest yet reported organometallic analogu
e of the Creutz-Taube ion [(NH3)5Ru(mu-pz)Ru(NH3)5]5+, has been charac
terized as a fully delocalized Mo0.5/Mo0.5 system by electrochemistry,
EPR, electronic and vibrational absorption spectroscopy.
