•A metaphosphate NaFe(PO3)3 compound is reported here for the first time.•Its structure and morphology are confirmed by XRD, SEM and TEM.•The vibrational spectra of NaFe(PO3)3 compound is resolved and summarized.•A typical paramagnetic behavior is observed for NaFe(PO3)3 within 10–300 K.•Its sodium deinsertion/insertion properties are also presented and discussed.
A metaphosphate NaFe(PO3)3 compound has been obtained by solid state method here. This title compound belongs to the orthorhombic structure with the space group of P212121 (No. 19) and lattice parameters of a = 14.3390(3) Å, b = 14.3374(2) Å, c = 14.3642(1) Å. Its structure can be described as made up of infinite (PO3)1− chains connected by FeO6 octahedra, while the monovalent Na cations are located in the tunnels determined by the connection of PO4 tetrahedrons and FeO6 octahedrons. Besides, the morphology, vibrational spectra, magnetic and sodium deinsertion/insertion properties of NaFe(PO3)3 compound are also presented and discussed here for the first time, which can provide more information about the physicochemical properties of this metaphosphate compound.
