The radical anion 1 ⊙⊖ is present as a monomer in dimethylformamide , as a dimer in aqueous dimethylformamide, and as stacks in aqueous NaCl solution according to ESR and UV/VIS spectra. The “π stacks” of 1 ⊙⊖ —actually a trianion—are soluble models for conducting organic charge‐transfer compounds. Thin, black, lustrous films of 1 ⊙⊖ exhibit a conductivity of 0.1 S cm −1 .
