CHEMISTS in Utah have discovered carbon-to-carbon bonds twice the length of any seen before. Joel Miller at the University of Utah in Salt Lake City found the long bonds in tetracyanoethylene (TCNE) and also in eight related compounds. Measuring 0.28 to 0.31 nanometres, the links were double the length of the bonds in diamond— usually considered the limit. In the online journal Angewandte Chemie, Miller described how his team discovered the bond in a TCNE dimer—two molecules joined together. “There’s this special interaction between the central atoms,
