Abstract
Dithiadiazafulvalenes (DTDAF) can be formed either chemically or electroche mically. Electrochemical investigations have been carried out on 2-ethylthi o-1,3-thiazolium salts to determine the redox behavior of dithiadiazafulval enes formed by cathodic coupling. Using an in situ method, the donor has be en trapped in the medium and a crystalline charge-transfer salt with TCNQ h as been isolated. The crystal structure and magnetic susceptibility data of this 1:3 complex established that the DTADF is in the dicationic state.
