Abstract

We report on the synthesis and characterization of the first polyoxo-noble-metalate-containing metal-organic framework (MOF) material, wherein the preformed MIL-101 has been impregnated with the discrete, cuboid-shaped polyoxopalladate [Pd₁₃Se₈O₃₂]^6- (Pd₁₃Se₈), leading to the composite Pd₁₃Se₈@MIL-101. This material was characterized by FTIR, TGA, elemental analysis, powder-XRD, N₂ sorption (BET), SEM-EDX, and XPS. Furthermore, the Pd₁₃Se₈@MIL-101 composite was shown to be an effective, stable, and recyclable heterogeneous precatalyst for the Suzuki-Miyaura cross-coupling reaction at room temperature utilizing environmentally benign solvents, such as water and methanol.
