A [3]radialene having strong electron-donor properties, the title compound 1, was formed upon reaction of lithium thioxanthenide with hexachlorocyclopropane after addition of BuLi. Cyclic voltammetry in CH2Cl2 gave two pairs of reversible waves corresponding to the formation of 1⊙⊕ and 12⊕. A thermally accessible triplet state, only 0.07 eV higher in energy than the singlet state, was established for dark blue 12⊕·2CF3CO by ESR spectroscopy. Thus, 1 might serve as a donor component for the preparation of organic ferromagnets.
