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.
It is a cage-like fused-ring structure which resembles a rugby ball, made of 25 hexagons and 12 pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge. A related fullerene molecule, named buckminsterfullerene (or C 60 fullerene) consists of 60 carbon atoms.
Alternatively, endohedral hydrogen fullerenes can be produced by opening and closing a fullerene by organic chemistry methods. A recent example of endohedral fullerenes includes single molecules of water encapsulated in C 60. [10] Noble gas endofullerenes are predicted to exhibit unusual polarizability.

In 2013 researchers discovered that asymmetrical fullerenes formed from larger structures settle into stable fullerenes. The synthesized substance was a particular metallofullerene consisting of 84 carbon atoms with two additional carbon atoms and two yttrium atoms inside the cage.
Fullerenes are a class of carbon allotropes that were first discovered in 1985 and are also an example of macromolecular cages. Buckminsterfullerene (C 60 ) and the 60 atoms of this molecule are arranged in a cage-like structure and the framework resembles a soccer ball; the molecule has an icosahedral symmetry.
A network solid or covalent network solid (also called atomic crystalline solids or giant covalent structures) [1] [2] is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.
A Stellantis joint venture with Samsung SDI has won a commitment from the U.S. government for up to a $7.54 billion loan to help build two electric vehicle battery plants in Kokomo, Indiana. The ...
