New lithium-niobium and lithium-tantalum phosphates Li{sub 1/4}M{sub 7/4}(PO{sub 4}){sub 3}(M = Nb, Ta) are synthesized by the solid-phase method. The compounds prepared are characterized using electron microprobe analysis, X-ray powder diffraction, and IR spectroscopy. The crystal structure of the Li{sub 1/4}Ta{sub 7/4}(PO{sub 4}){sub 3} phosphate is determined from the X-ray powder diffraction data (the Rietveld method) and belongs to the framework type. The framework of the structure consists of TaO{sub 6} and LiO{sub 6} vertex-shared octahedra and PO{sub 4} tetrahedra. The isostructural phosphates Li{sub 1/4}M{sub 7/4}(PO{sub 4}){sub 3} crystallize in the trigonal crystal system (space group R3-barc, Z = 6) and belong to the NaZr{sub 2}(PO{sub 4}){sub 3} structure type.
