摘要：

A high resolution C-13 NMR study of the 1:2 fullerene C-60 complex with [(C6H5)(3)P] AuCl (CTPG) has been pet-formed in the 180-350 K temperature range. Evidence for the CTPG polymerization, accompanied by C-60 protonation, is given. The C-60 rotation in the complex has been shown to be hindered, thermally activated, with the activation energy Delta E = 5.7 kcal/mol. The rotational correlation time, determined through the spin-lattice relaxation time measurements, varies from 10(-6) to 10(-9) s in the studied temperature range. No indication of an order-disorder transition in the C-60 sublattice has been found, contrary to previous optical studies. (C) 1998 Elsevier Science S.A. All rights reserved.
