An assembly of Keggin polyoxomolybdate and organic substrate (Hbipy)₃[PMo₁₂O₄₀] (1, bipy=2,2'-bipyridine) was synthesized and characterized by elemental analysis, infrared spectrum, and singlecrystal X-ray analysis. The ligand bipy of compound 1 was generated by a decarboxylation coupling reaction of H₂pdc (H₂pdc=pyridine-2,6-dicarboxylic acid) in situ under hydrothermal reaction conditions and the control experiments illustrate that La(NO₃)₃ or Ce(NO₃)₃, which does not appear in the final structure, is necessary for the decarboxylation coupling reaction. Moreover, compound 1 displays strong photoluminescence property in the solid state at room temperature.
