Na{sub 3} AZr(PO{sub 4}){sub 3} (A=Mg, Ni) phosphates were prepared at 750 deg. C by coprecipitation route. Their crystal structures have been refined at room temperature from X-ray powder diffraction data using Rietveld method. Li{sub 2.6}Na{sub 0.4}NiZr(PO{sub 4}){sub 3} was synthesized through ion exchange from the sodium analog. These materials belong to the Nasicon-type structure. Raman spectra of Na{sub 3} AZr(PO{sub 4}){sub 3} (A=Mg, Ni) phosphates present broad peaks in favor of the statistical distribution in the sites around PO{sub 4} tetrahedra. Diffuse reflectance spectra indicate the presence of octahedrally coordinated Ni{sup 2+} ions. - Graphical abstract: Structure of Na{sub 3} AZr(PO{sub 4}){sub 3} (A=Mg, Ni) phosphates. Display Omitted.
