AI Article Synopsis
- A polyoxopalladate compound with a high nuclearity, [Pd(II)(2)⊂{H(7)Pd(II)(15)O(10)(PO(4))(10)}](9-) {Pd(II)(17)}, consists of a {Pd(15)} host with a {Pd(2)} guest, and both have been characterized using various techniques, including X-ray crystallography.
- The encapsulated {Pd(2)} exhibits a close Pd(II)-Pd(II) distance within the {Pd(15)} host.
- Studies indicate a dynamic equilibrium between the empty host and the filled guest complex, with UV titrations showing a binding constant of approximately 10(3)
Article Abstract
A high-nuclearity polyoxopalladate compound, [Pd(II)(2)⊂{H(7)Pd(II)(15)O(10)(PO(4))(10)}](9-) {Pd(II)(17)}, comprising a {Pd(15)} host occupied by a {Pd(2)} guest and the parent pristine "empty" [H(7)Pd(II)(15)O(10)(P(V)O(4))(10)](13-) {Pd(15)} cluster have both been prepared and characterized by single-crystal X-ray crystallography, (31)P NMR, CSI-MS, and XPS. The encapsulated {Pd(2)} has a short Pd(II)-Pd(II) distance within the {Pd(15)} 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(3) for the guest Pd(II) ions, with a binding stoichiometry of almost 2.
