Abstract

Two new polyoxopalladates Na₂H₃[Pd ₁₂(μ₃-SeO₃)₈(μ₄-O) ₆(μ₃-O)₂Cr]·25H₂O (1) and Na₈H₇[Pd₁₂(μ₃-SeO ₃)₈(μ₄-O)₈In]₃· 24H₂O (2) have been synthesized by using Cr³⁺ and In ³⁺ ions as structural directing agents. The two polyoxopalladates have been characterized by single-crystal X-ray diffraction (SXRD), FTIR and UV/Vis spectroscopy, elemental analysis (EA), ESI-MS, and thermogravimetric analysis (TGA). Detailed SXRD analysis combined with the ESI-MS and a collision-induced dissociation (CID) fragmentation study shows that the coordination configurations of the central ions are different; this affects the stability and fragmentation mechanism of the clusters in the gas phase. This approach may help us to understand the dissociation chemistry and the catalysis mechanism of polyoxopalladates.
