Abstract

A high-nuclearity polyoxopalladate compound, [Pd<sup>II</sup><sub>2⊂</sub>{H<sub>7</sub>Pd<sup>II</sup><sub>15</sub>O<sub>10</sub>(PO<sub>4</sub>)<sub>10</sub>}]<sup>9−</sup> {Pd<sup>II</sup><sub>17</sub>}, comprising a {Pd<sub>15</sub>} host occupied by a {Pd<sub>2</sub>} guest and the parent pristine “empty” [H<sub>7</sub>Pd<sup>II</sup><sub>15</sub>O<sub>10</sub>(P<sup>V</sup>O<sub>4</sub>)<sub>10</sub>]<sup>13−</sup> {Pd<sub>15</sub>} cluster have both been prepared and characterized by single-crystal X-ray crystallography, <sup>31</sup>P NMR, CSI-MS, and XPS. The encapsulated {Pd<sub>2</sub>} has a short Pd<sup>II</sup>−Pd<sup>II</sup> distance within the {Pd<sub>15</sub>} 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. 10<sup>3</sup> for the guest Pd<sup>II</sup> ions, with a binding stoichiometry of almost 2.
