A silver filling: The π-acidic, trinuclear silver(I) pyrazolate [{[3,5-(CF3)2pz]Ag}3] readily reacts with simple electron-rich aromatic hydrocarbon compounds to form sandwich complexes. The type of complex formed depends on the solvent and the arene, and includes supramolecular stacks. Additionally, some of these complexes appear to have interesting luminescence properties.
