Abstract: Polar neutrals featuring an electronegative atom (O or N) are observed to form adducts with C60(2+) in the gas phase in selected-ion flow tube experiments at 294 +/- 3 K and 0.35 +/- 0.01 Torr. Addition is ascribed to the donation of an electron pair from the electronegative atom to the site of charge concentration on the fullerene ion's surface, forming a dative bond between the donor atom and a carbon atom of the fullerene shell and resulting in charge localization upon the donor atom. Secondary adducts are observed in many such reactions, but tertiary adducts are absent or are formed with considerably reduced efficiency, in accordance with the proposed method of addition. Observed association trends for C60.+ are also in accordance with the model proposed, and some preliminary measurements on association of C60.3+ are reported.
