Quantum‐chemical calculations at the CCSD(T)/cc‐pVTZ level of theory show that beryllium subfluoride, Be2F2, has a bond dissociation energy of De=76.9 kcal mol−1, which sets a record for the strongest Be−Be bond. The synthesis of this molecule should thus be possible in a low‐temperature matrix. The discus‐shaped species Be2B8 and Be2B7− possess the shortest Be–Be distance for a molecule in the electronic...
