Abstract
Discrete, organic anions provide an attractive alternative for the synthesis of molecular superconductors. We have previously prepared the first completely organic superconductor, β-(BEDT-TTF) 2 SF 5 CH 2 CF 2 SO 3 [BEDT-TTF, hereafter abbreviated ET is bis(ethylenedithio)tetrathiofulvalene]. Molecular metals which contain organic anions are essentially free of the magnetic impurities (i.e. Cu +2 ) that often plague the physical property studies of organic superconductors such as κ-(ET) 2 Cu[N(CN) 2 ]Br. We have undertaken a research effort aimed at the crystallization of conducting charge transfer salts which possess fluorinated alkylsulfonate anions as the charge compensating entities. Herein we report the extension of this work to include the synthesis and characterization of ET salts of the trifluoromethylsulfonate anions, CF 3 CRR'SO 3 - (R, R' = F, H).
