A trianionic gold-carborane cluster can trap hidride, fluoride and CO2

The Front Cover shows the interaction pattern between a triangular gold-carborane cluster trianion (host) and different cations, neutral molecules and anions (guests). The funnel above the cluster indicates that some of the guests, no matter their charge or size, can be trapped inside the void of the host. Cations form stable complexes according to the large electrostatic potential that favours attractive host···guest adducts, but some neutral and anionic guests can also be enclosed. Unexpectedly, hydride and fluoride are trapped forming tetraanionic species. Finally, among neutral molecules, only CO2 is trapped by the trinuclear cluster.
