After nearly 2 centuries of studying the chemistry of carbon, scientists may have identified a new type of bond connecting two carbon atoms. It's almost twice as long as the longest naturally occurring carbon-carbon bond, which occurs in diamonds.

The researchers stumbled upon stable carbon-carbon bonds of 0.283 to 0.309 nanometer (nm) in a family of novel magnetic plastics that they were studying. The typical carbon-carbon bond in diamond is just 0.154 nm.

Chemists had stretched carbon-carbon bonds only to a length of 0.173 nm, says Joel S. Miller of the University of Utah in Salt

Lake City.
