Abstract

The three novel, discrete palladium(II)-oxo clusters [CaPd12O8(PhAsO₃)₈]6^- (CaPd₁₂), [SrPd₁₂O₆(OH)₃-(PhAsO₃)₆(OAc)₃]4^- (SrPd¹²), and [BaPd₁₅O₁₀(PhAsO₃)₁₀]8^- (BaPd₁₅) encapsulating alkaline earth metal ions were prepared and fully characterized by a multitude of solution and solid-state physicochemical techniques. We have discovered a structure-directing template effect induced by the respective size of the alkaline earth guest ion, which determines the detailed condensation arrangement of the peripheral PdII-oxo shell. The unprecedented SrPd₁₂ with an open-shell type structure is of particular importance and reflects a successful strategy for deliberate design of new structural classes of polyoxo-noble-metalates. Furthermore, the unusual acetate-water ligand exchange phenomenon renders SrPd₁₂ as a promising candidate for noble-metal-based catalysis.
