Cluster reaction of [Ag8]−/[Cu8]− with chlorine: Evidence for the harpoon mechanism?

- We studied the reactions of coinage metal clusters with chlorine.
- We observe abnormal reactivity of [Ag8]−/[Cu8]− towards chlorine.
- We demonstrate the harpoon mechanism for the reactivity of [Ag8]−/[Cu8]− with Cl2.
- The alkali-metal-like clusters [Ag8]−/[Cu8]− validate the reactivity of superatoms.
