The Inorganic—free Organic Conductor α′—（ET）2C6H4（SO3）2：Its Synthesis,Structure,and Conductivity

A new ET based cation radical salt, α'-(ET)2C6H4(SO3)2 (ET = bis(ethylenedithio) tetrathiafulvalene) has been synthesized by oxidative electro-crystallization and the crystal structure determined to be in monoclinic system, P2/n space group. Its resistivity-temperature curve shows a semi-conductive behavior with a discontinuation at about 150K.
