abstract = {Five new compounds, [Rb(18crown-6)]3[C60] (1),
[Rb(18crown-6)]6[C60]2(C3H7NO)2(C4H8O)2 (2),
[Rb(benzo18crown-6)]6[C60]2(C2H8N2)5 (3),
[Cs(benzo18crown-6)]3C60(C2H8N2)2 (4), and
[Cs3(benzo18crown-6)5]C60(C2H8N2)(4.5+x) (5) were
synthesized and characterized by single-crystal X-ray
structure determination. All compounds contain discrete C60
anions, which are ordered in 1, 2, and 4, where direct
cation-anion contacts occur. The unit cells of 1 and 2
contain two independent fullerides, which coordinate to the
rubidium atoms either of two or of four [Rb(18crown-6)]
units. Owing to the presence of differently coordinated
fullerene units in compounds 1 and 2, a possible
disproportionation of C603– into C602– and C604–
anions is discussed. In 3 and 4 the C60 anions are
coordinated by three Rb and Cs atoms, respectively. In all
compounds the average charge of the anion is –3. Magnetic
data reveal a doublet spin state for 3. The EPR spectra are
discussed for compounds 3 and 5. The role of a dynamic
Jahn-Teller distortion is discussed, and we report the first
IR spectroscopic data of fullerene trianions, which have
been obtained in solution.},
