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 [Pd16 O24 (OH)8 ((CH3 )2 As)8 ] (Pd16 ) comprises a cyclic palladium-oxo unit capped by eight dimethylarsinate groups. The chloro-derivative [Pd16 Na2 O26 (OH)3 Cl3 ((CH3 )2 As)8 ] (Pd16 Cl) was also prepared, which forms a highly stable 3D supramolecular lattice via strong intermolecular interactions. The 24-palladium(II)-oxo cluster [Pd24 O44 (OH)8 ((CH3 )2 As)16 ] (Pd24 ) can be considered as a bicapped derivative of Pd16 with a tetra-palladium-oxo unit grafted on either side. The three compounds were fully characterized 1)â
in the solid state by single-crystal and powder XRD, IR, TGA, and solid-state 1 H and 13 Câ
NMR spectroscopy, 2)â
in solution by 1 H, 13 Câ
NMR and 1 H DOSY spectroscopic methods, and 3)â
in the gas phase by electrospray ionization mass spectrometry (ESI-MS).
