More than two decades after it was hypothesised, chemists have finally created a compound that contains two beryllium atoms joined by a metallic bond
A metallic bond between two beryllium atoms has been forged for the first time in the lab. The development could pave the way for the creation of new materials.
“Going back 100 years, chemists have been striving to understand how elements bond together, but there are still gaps in what we know. Beryllium is element number four in the periodic table, yet no one managed to bond two of these metal atoms together,” says, also at the University of Oxford, Aldridge and his colleagues have succeeded in doing that by synthesising a compound called diberyllocene.They started with a molecule that contains one beryllium and many hydrogen and carbon atoms.
Boronski says that beryllium has historically been understudied because it is toxic, but with proper safety protocols in place he and his colleagues found that they could make the new compound quickly and cleanly. The result matched the prediction of mathematical models from two decades ago that suggested such a compound could be stable.
