(ET)(3)(Br-3)(5): A metallic conductor with an unusually high oxidation state of ET (ET = bis(ethylenedithio)tetrathiafulvalene)
Electrochemical oxidation of ET with Br- in methanol/ CHCl3 yields a metallic crystalline product, (ET)(3)(Br-3)(5), in which the bromine chemical species is all Br-3(-) and the formal charge of ET becomes an unusually high value (5/3+).
