Abstract

A high-nuclearity polyoxopalladate compound, [Pd^II_2⊂{H₇Pd^II₁₅O₁₀(PO₄)₁₀}]⁹⁻ {Pd^II₁₇}, comprising a {Pd₁₅} host occupied by a {Pd₂} guest and the parent pristine “empty” [H₇Pd^II₁₅O₁₀(P^VO₄)₁₀]¹³⁻ {Pd₁₅} cluster have both been prepared and characterized by single-crystal X-ray crystallography, ³¹P NMR, CSI-MS, and XPS. The encapsulated {Pd₂} has a short Pd^II−Pd^II distance within the {Pd₁₅} host. Solution studies indicate that the empty host and filled guest complex are in equilibrium with each other, and UV titrations revealed a binding constant of ca. 10³ for the guest Pd^II ions, with a binding stoichiometry of almost 2.
