Radical salts of TTF derivatives with the metal–metal bonded [Re 2Cl 8] 2− anion

Abstract

Four new salts of the radical cations of TMTSF (tetramethyltetraselenafulvalene), TMTTF (tetramethyltetrathiafulvalene), BEDT-TTF (bisethylenedithiotetrathia-fulvalene) (ET) and o-Me 2TTF ( o-4,4′-dimethyltetrathiafulvalene) with the metal–metal bonded dianion [Re 2Cl 8] 2− were synthesized, and their structures and physical properties investigated. The structures of these semiconducting salts feature one-dimensional stacking of the donor molecules interleaved with [Re 2Cl 8] 2− anions and interstitial solvent molecules.
