Confining the spin between two metal atoms within the carbon cage: redox-active metal-metal bonds in dimetallofullerenes and their stable cation radicals.

ABSTRACT: Lanthanide-lanthanide bonds are exceptionally rare, and dimetallofullerenes provide a unique possibility to stabilize and study these unusual bonding patterns. The presence of metal-metal bonds and consequences thereof for the electronic properties of M₂@C₈₂ (M = Sc, Er, Lu) are addressed by electrochemistry, electron paramagnetic resonance, SQUID magnetometry and other spectroscopic techniques. A simplified non-chromatographic separation procedure is developed for the isolation of Er₂@C₈₂ (C_s(6) and C_3v(8) cage isomers) and Sc₂@C₈₂ (C_3v(8) isomer) from fullerene mixtures. Sulfide clusterfullerenes Er₂S@C₈₂ with C_s(6) and C_3v(8) fullerene cages are
