Crystal structures and electrical conducting properties of the first molecular metals based on a novel electron acceptor, 4-oxo-2,6-bis(dicyanomethylene)-2,6-dihydrocyclopentadithiophene (CPDT)

Abstract

A novel electron acceptor CPDT has been synthesized; the Fermi surfaces of the metallic anion radical salts of CPDT are purely one-dimensional, while the acceptor molecules form rigid and tight two-dimensional networks in the crystal structures of the salts.
