- Buckyball / Fullerene Designations:
Chemical Name: Carbon
Chemical Formula: C60, C70
- Buckyball / Fullerene Description:
1) Discovered in 1985 by Messrs. R. Smalley, R. Curl and H. Kroto. Another group of chemists in Germany had produced pure fullerenes in 1980. Large clusters or aggregates of carbon molecules that are spherical or roughly spherical in shape. A carbon atom sits at each vertex of a buckyball, bonding with three of its neighbors.
2) Fullerenes are transparent over a wide spectral range extending from the mid-infrared throughout the visible. They possess a high thermal and oxidative stability compared to many other organic materials. Extremely resilient and relatively impervious to damage. They do not react with corrosive compounds and are capable of absorbing and releasing electrons without being harmed or change.

- Boron Buckyball Description:
A new type of buckyball utilizing boron atoms instead of the usual carbon has been predicted and described by researchers at Rice University. The B-80 structure, with each atom forming 5 or 6 bonds, is predicted to be more stable than the C-60 buckyball. One reason for this given by the researchers is that the B-80 is actually more like the original geodesic dome structure popularized by Buckminster Fuller which utilizes triangles rather than hexagons. However, this work has been subject to much criticism by quantum chemists as it was concluded that the predicted Ih symmetric structure was vibrationally unstable and the resulting cage undergoes a spontaneous symmetry break yielding a puckered cage with rare Th symmetry (symmetry of a volleyba. The number of six atom rings in this molecule is 20 and number of five member rings is 12. There is an additional atom in the center of each six member ring, bonded to each atom surrounding it.
