摘要
Three new suprarnolecular networks based on paratungstate and N-donor bridging ligands, [H2bpmp]2,5H[H2W12O40]·2H20（1）, [H2（bpp）]2[H（py-CH3）]0.25 [H（py-C2Hs）]0.25H1.5[H2W12O40]·4H2O（2） and [H2pip]3[H2W12O40]（3）[bpmp=N,N＇-bis（4-pyridylmethyl）piperazine; bpp=l,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-dimen- sional suprarnolecular networks based on [H2W12O40]^6- and the protonated N-donor ligands via the N-H.…O-W hydrogen bonds and/or π…πstacking interactions. Their luminescent properties were investigated.
