Organic metals: a new series of radical-cation salts based on an alkylated tetrathiafulvalene

Abstract

A new series of radical-cation salts, prepared by electro-oxidation, of 2-(4,5-dimethyl-1,3-dithiol-2-ylidene)-5,6-dihydro-4H-cyclopenta-1,3-dithiole exhibit very promising d.c. electrical conductivity and e.s.r. characteristics (linewidth and g-factor); an antiferromagnetic state probably exists at low temperature.
