Three new suprarnolecular networks based on paratungstate and N-donor bridging ligands,[H2bpmp]25H[H2W12O40].2H2O( 1 ),[H2(bpp)] 2[H(py-CH3)]0.25[H(py--C2H5)]0.25H1.s[H2W12O40].4H2O(2) and [H2pip]3[H2W12O40](3)[bpmp=N,N1-bis(4-pyridylmethyl)piperazine; bpp=1,3-bis(4-pyridyl)propane; py=pyridine;pip=piperazine] were prepared by the hydrothermal synthesis and characterized by elemental analysis,infrared(IR),thermogravimetric(TG) analysis and single-crystal X-ray diffraction(XRD).All the compounds show high-dimensional supramolecular networks based on [H2W12O40]6- and the protonated N-donor ligands via the N-H…O-W hydrogen bonds and/or π…π stacking interactions.Their luminescent properties were investigated.
