| 摘 要： | A novel open-franmework vanadium(IV) phosphate (H3NCH2CH2NH3)3[(VO)4(PO4)2(HPO4)4](short for V2P3-en)has been prepared.It is synthesized hydrothermally in the presence of ethylenediamine(en)at 170℃ for 5 days by self-assembly form sturcturally simple precursors V2O5,H3PO4and H2O.The compound is characterized by means of Fourier transform-infrared spectroscopy(FT-IR),Thermogravimetry-differenti8al thermal analysis(TG-DTA),X-ray powder diffraction analysis(XRD) and Scanning electron microscopy (SEM) .Furthermore,the composition-structure-thermal stability relation of V2P3-en is exploed in terms of crystal chemistry,and the potential approach to the enhancement of its thermal stability is proposed.

| Abstract: | A novel open-framework vanadium(Ⅳ) phosphate (H3NCH2CH2NH3)3[(VO)4(PO4)2(HPO4)4] (short for V2P3-en) has been prepared. It is synthesized hydrothermally in the presence of ethylenediamine (en) at 170℃ for 5 days by self-assembly from structurally simple precursors V2O5, H3PO4 and H2O. The compound is characterized by means of Fourier transform-infrared spectroscopy (FT-IR), Thermogravimetry-differential thermal analysis (TG-DTA), X-ray powder diffraction analysis (XRD) and Scanning electron microscopy (SEM). Furthermore, the composition-structure-thermal stability relation of V2P3-en is explored in terms of crystal chemistry, and the potential approach to the enhancement of its thermal stability is proposed. |
