A New Dimension in Cyclic Coinage Metal Pyrazolates: Decoration with a Second Ring of Coinage Metals Supported by Inter-ring Metallophilic Interactions
When pyrazolate ligands with thioether chelate arms are used in cyclic coinage metal pyrazolates [Au(mu-pz)]IV, the inner gold ring can be framed with an outer silver ring to give novel heterometallic double-crowned complexes [AuAg(mu-L-x) (BF4)](4). They feature short intramolecular in-plane Ag-Au interactions, are stable as octanuclear species in solution, and show promising luminescence properties.
