IUPAC Name
(C60-Ih)[5,6]fullerene

Color/Form
Spherical aromatic molecule with a hollow truncated-icosahedron structure, similar to a soccer ball. /C60/;Polyhedral cages made up of entirely five-and six-membered rings ... fullerenes contain 2(10+N) carbon atoms ... the smallest conceivable fullerene is C20, and all fullerenes must contain an even number of carbon atoms.;Solutions of C60 fullerene in hydrocarbon solvents are magenta ... C70 fullerene are port-wine red. In some solvents C76 /and C84/ fullerene gives yellow-green solutions ... C82 fullerene has a less greenish tinge. Solutions of C78 fullerene are golden chestnut brown

Melting Point
At 260 K, a first-order phase transition from face-centered cubic crystal structure to a simple cubic structure is observed, accompanied by a lattice contraction. ... At 90 K the molecules rearrange to attain the best global minimum. ... At this temperature, the rotational degrees of freedom are frozen, and the solid structure is designated as a pseudo-face-centered cubic crystal structure. C70 Fullerene is rotationally disordered at room temperature and undergoes a transition to a low-temperature phase.

Solubility
Virtually insoluble in acetone, ethers, and alcohols;/C60/ is essentially insoluble in polar solvents, sparingly soluble in alkanes. In aromatic solvents and in carbon disulfide appreciable solubilities are observed.;Solubility (in mg/mL) of (60)fullerene: n-pentane 0.005; n-hexane 0.043; cyclohexane 0.036; n-decane 0.071; decalins 4.6; dichloromethane 0.26; carbon disulfide 7.9; dichloromethane 0.26; chloroform 0.16; tetrachloromethane 0.32; tetrahydrofuran 0.0; benzene 1.7; toluene 2.8; tetralin 16; benzonitrile 0.41; anisole 5.6; 1,2-dichlorobenzene 27; 1-methylnaphthalene 33; 1-chloronaphthalene 41; acetone 0.001; methanol 0.0;The solubility of C70 decreases relative to that of C60 ... roughtly 50% of the values for C60 in toluene, chlorobenzene, 1,2-dichlorobenzene, trichloromethane and hexane. Water solubility is greatly increased by the addition of hydroxyl groups either to the cage (giving fullerenols) or having them present in addends;Solubilities in various solvents at 25 ℃: ethanol (1.4 mg/L), octanol (42.9 mg/L), distilled octanol (38.9 mg/L), water-saturated octanol (34.7 mg/L), tetrahydrofuran (11 mg/L), toluene (3000 mg/L), water-saturated toluene (2430 mg/L);Calculated solubility in water at 25 ℃ = 7.42 ng/L (water-phase of water-octanol), based on measured values in octanol (of octanol-water phase) and octanol-water partition coefficient
