The high pure Fe(PO3)3 with three-dimensional networks structure was synthesized by a novel thermal decomposition of phosphonate. Briefly, the iron phosphonate (FeIII-edtmpH5) complex was synthesized by using FeCl3 and ethylenediamine-tetramethylene phosphonic acid (edtmpH8) as starting materials. The composition and structure of FeIII-edtmpH5 complex is characterized by Fourier transform infrared spectroscopy (FT-IR), electrospray ionization/mass spectrometry (ESI/MS) and thermogravimetry-,differential thermal analysis (TG-DTA). Then, the Fe(PO3)3 is obtained by thermal decomposition of FeIII-edtmpH5 complex in air atmosphere. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements show that the obtained Fe(PO3)3 possesses high purity, good crystallinity and particular three-dimensional networks morphology.
