Abstract: We report on the synthesis, structure, and physicochemical characterization of the first three examples of neutral palladium-oxo clusters (POCs). The 16-palladium(II)-oxo cluster [Pd16O24(OH)(8)((CH3)(2)As)(8)] (Pd-16) comprises a cyclic palladium-oxo unit capped by eight dimethylarsinate groups. The chloro-derivative [Pd16Na2O26(OH)(3) Cl-3 ((CH3)(2) As)(8)] (Pd16Cl) was also prepared, which forms a highly stable 3D supramolecular lattice via strong intermolecular interactions. The 24-palladium(II)-oxo cluster [Pd24O44(OH)(8)((CH3)(2)As)(16)] (Pd-24) can be considered as a bicapped derivative of Pd-16 with a tetra-palladium-oxo unit grafted on either side. The three compounds were fully characterized 1) in the solid state by single-crystal and powder XRD, IR, TGA, and solid-state H-1 and C-13 NMR spectroscopy, 2) in solution by H-1, C-13 NMR and H-1 DOSY spectroscopic methods, and 3) in the gas phase by electrospray ionization mass spectrometry (ESI-MS).
