Despite strong twisting of the conjugated system , the tetrathiafulvalene homologue 1 reacts with the electron acceptor tetracyanoquinonodimethane to give the dication 1 2⊕ . The anthracene moiety is embedded in the 1 2⊕ [(TCNQ) 4 ] 2⊖ , and the dithiol rings are twisted 86° with respect to the anthracene plane: The 1:4 stoichiometry of the highly conductive salt (σ 300K = 60S cm −1 ) is very unusual for TCNQ complexes.
