M. Iyoda et al., Conducting charge-transfer and radical ion salts based on bitetrathiafulvalenes; an approach to organic metals using stoichiometry control, J MAT CHEM, 9(2), 1999, pp. 335-337
Charge-transfer and radical ion salts of 4,5,4''',5'''-tetram-ethylthio-, 4
,5,4''',5'''-bis (ethylenedithio)-, and 4,5,4"',5"'-bis (ethylenedioxy)-4',
4 "-bitetrathiafulvalenes showed fairly high electric conductivities, refle
cting the effect of stoichiometry control.
