An assembly of Keggin polyoxomolybdate and organic substrate (Hbipy)3[PM01204o] (1, bipy = 2,2'- bipyridine) was synthesized and characterized by elemental analysis, infrared spectrum, and single- crystal 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.
