| dc.description.abstractEn | Sr<sub>0.5</sub>Zr<sub>2</sub>(AsO<sub>4</sub>)<sub>3</sub><sup> </sup>arsenate was prepared and structurally characterized by powder X-ray diffraction<sup> </sup>and by Raman and infrared spectroscopies. Its structure, which belongs<sup> </sup>to the Nasicon-type family, was refined by the Rietveld method<sup> </sup>in the R-3 space group, from X-ray powder diffraction data.<sup> </sup>The hexagonal unit-cell parameters were determined to be <i>a</i><sub><i>h</i></sub>=8.965(2) Å, <i>c</i><sub><i>h</i></sub>=23.955(6) Å,<sup> </sup><i>V</i>=1667.43(6) Å<sup>3</sup>, and <i>Z</i>=6. The structure is formed by an ionic<sup> </sup>three-dimensional network of AsO<sub>4</sub> tetrahedra and ZrO<sub>6</sub> octahedra linked by<sup> </sup>corners with Sr<sup>2+</sup> ions occupying half of the M1 sites<sup> </sup>in an ordered manner. Raman and infrared spectra were recorded<sup> </sup>and assignments of the stretching and bending vibrations of the<sup> </sup>AsO 3/4- tetrahedra were made. The number of the peaks observed is in good agreement with that predicted by the factor-group analysis of the R-3 space group. | |
