First-ever metallic bond formed between beryllium atoms.

Chemists at the University of Oxford have successfully bonded two beryllium atoms for the first time using a multi-stage process that involves building two molecules with each made up of a single beryllium atom and several carbon and hydrogen atoms. The team mixed the two molecules together with a chemical made by bonding dual magnesium atoms together, resulting in the creation of a crystal compound called diberyllocene. The team established safety protocols to conduct the procedure safely and found that math models used to make predictions decades ago proved to be correct.

Chemists achieve stable beryllium bond after 50-year quest

Researchers at the University of Oxford have successfully isolated the first stable compound with a beryllium-beryllium bond, diberyllocene, using a dimeric magnesium(I) complex. The synthesis of diberyllocene will help answer questions about the fundamental nature of beryllium-beryllium bonding that were posed over a century ago. The compound features two half-sandwich (cyclopentadienyl)beryllium units linked through a beryllium-beryllium bond, which was found to be 2.05Å in length. The researchers also concluded that diberyllocene was a reductant that could be used to synthesise other beryllium-metal bonds.
