The cation radical (CR) and charge transfer (CT) salts of 7,10-dithiafluoroanthene with various inorganic and organic accepters were prepared either by electrocrystallization in the presence of tetraalkylammonium salts or recrystallization of the mixture of donor and accepters. The structures of these CR and CT salts were determined by X-ray crystallographic analysis and the conductivities of those salts were measured by a four probe method using compaction pellets.
