Unsymmetrically substituted dithiadiselenafulvalene donors for organic metals. Synthesis and conductivity of the charge-transfer salts

Abstract
New unsymmetrical dithiadiselenafulvalene donors and their radical cation salts with inorganic anions have been prepared; among the salts dimethyl(ethylenedithio)dithiadiselenafulvalene salts exhibit the highest electrical conductivity.
