Molecular conductors with anti-7,7′:8,8′-bis(dithio)bis(7,8-dicarbaundecaborate) anion

New radical cation salts (BEDT-TTF)2[anti-7,7′:8,8′-bis(dithio)bis(7,8-dicarba-undecaborate)] and (TMTTF)2[anti-7,7′:8,8′-bis(dithio)bis(7,8-dicarbaundecaborate)] were obtained by electrocrystallization from solution of bis(ortho-carboranyl-1,2-dithiolate)cobalt(II) complex (Me4N)2[Co(1,2-S2C2B10H10)2] and BEDT-TTF or TMTTF, respectively, in acetonitrile – 1,1,2-thrichloroethane. The process is accompanied with the complex demetallation, partial deboronation of the carborane cage and oxidation of dithiolate to cyclic bis(disulfide). X-ray crystal structures and electrical conductivities of the compounds synthesized were determined.
