“…Although detailed analysis was complicated by poor solubility and the presence of products formed from C 70 , isomer 4, with D 3d symmetry, was proposed. Other work including electron and X-ray diffraction studies [70] also supported the assignment of the D 3d structure 4. It is interesting that a se- cond D 3d structure 2 is among the most stable isomers known.…”

“…The selective reduction of C 70 13 C NMR (35 resonances of equal intensity, indicative of C 2 symmetry), and 1 H-coupled 13 C NMR spectroscopy. Since only one-and two-bond couplings were observed at the sp 3 -carbon resonances, the symmetry-equivalent pairs of adjacent protonated carbon atoms are located more than five bonds apart, placing them at opposite poles of the molecule.…”

“…bond equal to 0.174 nrn, which is much greater than the standard length of a covalent bond (0.149 nm) equal to the sum of the covalent radii. It is known that hydrated filllerene C6o can be synthesized by various methods including the method tbr direct high-temperature saturation [I, 2,8,9]. As a result of synthesis at a high pressure (several hundred MPa) the authors of [8] have obtained the most saturated hydride C(,,H3a with a b.c.c, lattice (a = 1.185 nm) differing from the lattice of the original ft, llerene C~, o and having a molecular density 26% lower than in the original fullerene.…”

.Synthesized Cr fluoride and C~,,D~, C~,oDis and Ct,oD36 deuterides of fullerene C~, o are described. All the compounds have a f.c.c, structure (like the original C~,. ) with periods a = 1.726, 1.423, 1.448, and 1.498 nm, respectively. Powder neutron diffraction diagrams are described on the basis of a double-shell model, i.e., an internal carbon sphere with a radius of 0.356 nm and a fluorine or deuterium sphere with a radius of 0.530 or 0.470 nm, respectively. The structure of the fluorinated and deuterated fullerencs is discussed with allowance for the existence of covalent bonds between the shells inside the molecule and van der Waals bonds between the peripheral atoms of one molecule and neighbor molecules. The description of the structure of the fullerene derivatives is based on the assumption that deuterium or fluorine atoms are absent on the external shell in the places of contact with the neighbor molecule. The low-temperature behavior of the C~,0F4s and C~,~D3~ , compounds is studied. A phase transformation in the Cr,oFss flt, oridc at T = 270 K is described, which is similar to the transformation of an orientation type in isostructural fullcrene C,. at a close temperature. The observed changes in the intensities of the diffraction peaks are described under the assumption that the phase transformation is accompanied by a decrease in the volt, me at invariable radii of the carbon and fluorine spheres. Similar changes in the intensity have been determined in the C~,I~D3~ , compound.

“…As the number of adducts increases, the fullerene derivative recovers a more symmetric structure and isotropy, leading to higher crystal symmetries (e.g. bcc in the C 60 H 36 fullerane [70]). The crystal structure formed by C 60 derivatives with larger sideadducts is in general not unique.…”

Abstract:We review the fundamental properties and main applications of organic derivatives and complexes of fullerenes in the solid-state form. We address in particular the structural properties, in terms of crystal structure, polymorphism, orientational transitions and morphology, and the electronic structure and derived properties, such as chemical activity, electrical conduction mechanisms, optical properties, heat conduction and magnetism. The last two sections of the review focus on the solid-state optoelectronic and electrochemical applications of fullerene derivatives, which range from photovoltaic cells to field-effect transistors and photodetectors on one hand, to electron-beam resists, electrolytes and energy storage on the other.
