Alternating layers of radicals of the π‐electron donor 1 and of polyoxonions [CoW 12 O 40 ] 6− ( 2 , polyhedral representation) are contained in the title compound. Thus, organic charge carriers and inorganic electron‐acceptor components lie next to each other. Since the polyoxometalates can accommodate different metal ions at specific sites, such anions are attractive precursors for the preparation of radical cation salts with new electrical and magnetic properties.
