Multiply charged negative ions are ubiquitous in nature. They are stable as crystals because of charge compensating cations; while in solutions, solvent molecules protect them. However, they are rarely stable in the gas phase because of strong electrostatic repulsion between the extra electrons. Therefore, understanding their stability without the influence of the environment has been of great interest...
Mehrfach geladene Anionen sind wegen starker elektrostatischer Abstoßung in der Gasphase instabil. Q. Wang, P. Jena et al. beschreiben in der Zuschrift auf S. 13606 das rationale Design der BeB11(X)123−‐Trianionen (X=CN, SCN, BO), die in der Gasphase gegen eine spontane Elektronenabgabe um 2.65 eV stabilisiert sind. Bezüglich ihrer chemischen Eigenschaften ähneln die Trianionen den Gruppe‐15‐Elementen...
