Both freshly sublimed C-60 and "off-the-shelf" C-60 were reduced with the alkali metals in hexamethylphosphoramide (HMPA). When pure C-60 is reduced to its trianion radical, it condenses with a molecule of HMPA to yield C-60(3-)(HMPA)(.), which exhibits a typical EPR pattern for a system with a doublet multiplicity and hyperfine splitting from the P-31 (a31(P) 0.93 G). When Rb or Cs serves as the reducing metal, hyperfine is observed from the metal cation (a(Cs)(133) 0.78 G, a(87)(Rb) = 1.393 G), which is involved in tight ion association with the P=O moiety (C-60(3-)(HMPA)(.),M+). The small cations do not form intimate ion pairs, and both C-60(3-)(HMPA)(.) and C-60(3-)(HMPA)(2)(.) are present in solution when M = Na or Li. The latter species exhibits an EPR splitting from two (31)Ps. The "off-the-shelf" C-60 contains C120O as an impurity. Extensive reduction of this impurity results in a charged multianionic state where very large splittings from three (31)Ps are observed.
