“…Theoretical calculation of the endohedral mono-metallofullerenes suggests that reduction and oxidation takes place on the carbon cage 17,18,20,22,23 Figure 1 (M = La) 17 ). Therefore, these ions do not have the characteristics of a radical, as confirmed by ESR 25 and NMR 17Í23 study. Subsequently, a convenient method for isolating endohedral metallofullerenes from soot extracts was developed, in which the selective reduction of the endohedral metallofullerenes with low reduction potentials takes place.…”

This account describes the redox behaviors of endohedral metallofullerenes having remarkable electron-accepting and -donating abilities, which accompany the transformation between their paramagnetic and diamagnetic states. A convenient method of isolating endohedral metallofullerene by means of selective reduction from carbon soot extracts is also developed. Successful isolation in large amount by utilizing this method allows examination of the construction of a supramolecular system based on endohedral metallofullerenes with azacrown ethers, unsaturated thiacrown ethers, and organic donor molecules. Consequently, endohedral metallofullerenes are revealed to form an inclusion complex with the crown compounds by electron transfer, and a stimuli-responsive reversible electron transfer system is constructed by using endohedral metallofullerenes and organic donors. These electron transfers proceed readily even in the ground state, which is a specific phenomenon for endohedral metallofullerenes.

“…[1][2][3][4][5][6][7][8] Many experimental results have shown that a group-III metal ͑M ϭSo, Y, La͒ or lanthanide atom could be attached to a fullerene C 82 molecule. 1-8 X-ray absorption fine-structure ͑EXAFS͒ studies on Y@C 82 have provided strong evidence that the metal atom is located inside the fullerene cage.…”

We have studied the initial stage growth of endohedral metallofullerene Nd@C 82 on crystalline C 60 films using in situ ultrahigh vacuum scanning tunneling microscopy. We find that Nd@C 82 molecules aggregate into two-dimensional close-packed configurations. Over 60% of molecules form triangle-shaped trimers with identical orientation with respect to the underlying C 60 films. Our observations are attributed to a permanent dipole moment of Nd@C 82 molecules. We also use a dipole-dipole interaction model to calculate their binding energy and the result shows that the dipole moments of Nd@C 82 molecules will displace off the molecular center while they form trimers. ͓S0163-1829͑98͒02728-3͔

“…The name 'metallo-fullerenes' has now become common to denote fullerenes with a metal atom inside. The first type of metallofullerene extracted from fullerene soot was lanthanum-fullerene La@C 82 [86][87][88][89] followed a short time later by scandium fullerene Sc@C 82 [90,91] and yttrium fullerene Y@C 82 [90,92].…”

A review of some of the solid state and the magnetic properties of fullerenes is presented. We summarise and discuss experimental results on magnetism of pure C60, C70 and higher fullerenes. The main features of the structure and the magnetic properties of intercalated fullerenes, such as metallofullerenes, TDAE-C60 and polymeric A1C60, are presented. Attention is also paid to the mixed state properties of fullerene superconductors, especially to the evaluation of the critical fields and the characteristic lengths of these materials. Some new experimental results on this subject are also presented.
