Indium in Polyoxopalladate(II) Chemistry: Synthesis of All-Acetate-Capped [InPdO(OAc)] and Controlled Transformation to Phosphate-Capped Double-Cube and Monocube.

We have prepared the indium(III)-centered, all-acetate-capped polyoxopalladate(II) nanocube [InPdO(OAc)] (), which can be further used as precursor to form the phosphate-capped (i) double-cube [InPdO(OH)(PO)(POOH)] () and (ii) monocube [InPdO(PO)] (). All three novel polyoxopalladates (POPs) were synthesized using conventional one-pot techniques in aqueous solution and characterized in the solid state (single-crystal XRD, IR, elemental analysis), in solution (In, P, and C NMR), and in the gas phase (ESI-MS).
