摘要: Abstract Addition of carbon tetrachloride or chloroform to acetonitrile solutions the bis(fulvalene)dicobalt monocation results in appearance new absorption features which are attributed formation electron donor-acceptor complexes. The association constants these complexes aer 2.36 /mole fraction (carbon tetrachloride) and 2.74 (chloroform). Excitation bands oxidation dication with high quantum yields. A complex is also formed when sodium tetraphenylborate added dication. Spectroscopic determination constant yields a value 26.3 fraction. ion-pair for bis(fulvalene) dicobalt monocation. Biphenyl found photolyzed as byproduct anion.
