A Diels–Alder adduct of [60]fullerene and a tetrathiafulvalene (TTF) derivative is synthesised by direct reaction of [60]fullerene with a TTF diene precursor; the crystal structure of the formal intermediate 1,3-dithiole-2-thione derivative of [60]fullerene reveals short contacts between the [60]fullerene and 1,3-dithiole-2-thione moieties.
