1A very short Be-Be distance but no bond: Synthesis and bonding analysis of Ng-Be2O2-Ng' (Ng, Ng' = Ne, Ar, Kr, Xe).

Frenking G1, Li J2, Zhou M2.

Chemistry. 2016 Dec 23. doi: 10.1002/chem.201605994. [Epub ahead of print]

Short interatomic distances below standard values for a single bond are usually identified with double or triple bonds. Here, we report the synthesis and spectroscopic characterization of a molecule where the distance between two beryllium atoms is shorter than a standard double bond but there is no bond. The cyclic diberyllium dioxide Be2O2 molecule which is coordinated by two noble gas atoms in Ng-Be2O2-Ng' (Ng, Ng' = Ne, Ar, Kr, Xe) was isolated and spectroscopically identified in low-temperature matrices.
