Discovery of Polyoxo-Noble-Metalate-Based Metal–Organic Frameworks

Here
we report on the synthesis, structure, and characterization
of the first example of a poly­oxo­palladate (POP)-based
metal-organic framework (MOF). This novel class of materials comprises
discrete polyoxo-13-palladate­(II) nanocubes [Pd13O8(AsO4)8H6]8– decorated by four Ba2+ ions on each of two opposite faces.
These secondary building units (SBUs) are linked to each other via
rigid linear organic groups, resulting in a stable 3D POP-MOF framework,
which exhibits interesting sorption as well as catalytic properties.
