摘要：
A new Nasicon phosphates series [Na3+xCr2-xCox(PO4)(3)(0 <= x <= 1)] was synthesized by a coprecipitation method and structurally characterized by powder X-ray, diffraction. The selected compound Na3.5Cr1.5Co0.5(PO4)(3) (x=0.5) crystallizes in the R (3) over barc space group with the following hexagonal unit-cell dimensions: a(h)=8.7285(3) angstrom, c(h)=21.580(2) angstrom, V=1423.8(1) angstrom(3), and Z=6. This three-dimensional framework is built of PO4 tetrahedra and Cr/CoO6 octahedra sharing corners. Na atoms occupy totally M(1) sites and partially M(2) sites.
