Buckminsterfullerene is a truncated icosahedron with 60 vertices, 32 faces (20 hexagons and 12 pentagons where no pentagons share a vertex), and 90 edges (60 edges between 5-membered & 6-membered rings and 30 edges are shared between 6-membered & 6-membered rings), with a carbon atom at the vertices of each polygon and a bond along each polygon ...
60 in extra virgin olive oil, showing the characteristic purple color of pristine C 60 solutions. Fullerenes are soluble in many organic solvents, such as toluene, chlorobenzene, and 1,2,3-trichloropropane. Solubilities are generally rather low, such as 8 g/L for C 60 in carbon disulfide.
Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.
The example above would then be denoted M@C 60 if M were inside the carbon network. A more complex example is K 2 (K@C 59 B), which denotes "a 60-atom fullerene cage with one boron atom substituted for a carbon in the geodesic network, a single potassium trapped inside, and two potassium atoms adhering to the outside."

The first fullerene molecule to be discovered, and the family's namesake, buckminsterfullerene (C 60), was prepared in 1985 by Richard Smalley, Robert Curl, James Heath, Sean O'Brien, and Harold Kroto at Rice University. [1] A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, tube, and many other ...
Sep. 1—Carbon capture and cover crops were among the topics discussed by panelists at the climate smart agriculture panel at Dakotafest on Wednesday morning. And they said that reducing carbon ...
The same goes for workers in the railroad industry, who don’t receive Social Security but have benefits with the Railroad Retirement Board (so long as they have more than 10 years of service).
The C 70 molecule has a D 5h symmetry and contains 37 faces (25 hexagons and 12 pentagons) with a carbon atom at the vertices of each polygon and a bond along each polygon edge. Its structure is similar to that of C 60 molecule (20 hexagons and 12 pentagons), but has a belt of 5 hexagons inserted at the equator. The molecule has eight bond ...
