    A New Dimension in Cyclic Coinage Metal Pyrazolates: Decoration with a Second Ring of Coinage Metals by Inter-ring Metallophilic Interactions

    No full text
    When pyrazolate ligands with thioether chelate arms are used in cyclic coinage metal pyrazolates [Au(μ-pz)]n, the inner gold ring can be framed with an outer silver ring to give novel heterometallic double-crowned complexes [AuAg(μ-Lx)(BF4)]4. They feature short intramolecular in-plane Ag–Au interactions, are stable as octanuclear species in solution, and show promising luminescence properties
