60-I h)[5,6]fullerene. The name of the point group should be retained in any derivative of said fullerene, even if that symmetry is lost by the derivation. To indicate the position of substituted or attached elements, the fullerene atoms are usually numbered in a spiral path, usually starting with the ring on one of the main axes.
Fullerene C 60. Fullerene chemistry is a field of organic chemistry devoted to the chemical properties of fullerenes. [1] [2] [3] Research in this field is driven by the need to functionalize fullerenes and tune their properties. For example, fullerene is notoriously insoluble and adding a suitable group can enhance solubility. [1]
A transition metal fullerene complex is a coordination complex wherein fullerene serves as a ligand. Fullerenes are typically spheroidal carbon compounds, the most prevalent being buckminsterfullerene, C 60. [2] One year after it was prepared in milligram quantities in 1990, [3] C 60 was shown to function as a ligand in the complex [Ph 3 P] 2 ...
Besides unfilled fullerenes, endohedral metallofullerenes develop with different cage sizes like La@C 60 or La@C 82 and as different isomer cages. Aside from the dominant presence of mono-metal cages, numerous di-metal endohedral complexes and the tri-metal carbide fullerenes like Sc 3 C 2 @C 80 were also isolated. In 1999 a discovery drew ...
Heterofullerenes are classes of fullerenes, at least one carbon atom is replaced by another element. [1] [2] Based on spectroscopy, substitutions have been reported with boron (borafullerenes), [3] [4] nitrogen (azafullerenes), [5] [6] oxygen, [7] arsenic, germanium, [8] phosphorus, [9] silicon, [10] [11] iron, copper, nickel, rhodium [11] [12] and iridium.

In chemistry, a metallofullerene is a molecule composed of a metal atom trapped inside a fullerene cage.. Simple metallofullerenes consist of a fullerene cage, typically C 80, with one or two metal atoms trapped inside.

C 70 fullerene is the fullerene molecule consisting of 70 carbon atoms. 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.
