Crystal Structure of the Compound Sc<sub>1.33</sub>Pd<sub>3</sub>Al<sub>8</sub> with Layers of R Atoms and Al<sub>3</sub> Triangles
Abstract
<jats:p>The crystal structure of the new ternary aluminide Sc<jats:sub>1.33</jats:sub>Pd<jats:sub>3</jats:sub>Al<jats:sub>8</jats:sub>was refined by the Rietveld method from X-ray powder diffraction data. It crystallizes with a Gd<jats:sub>1.33</jats:sub>Pt<jats:sub>3</jats:sub>Al<jats:sub>8</jats:sub>-type structure:<jats:italic>hR</jats:italic>51-14.00,<jats:italic>R-</jats:italic>3<jats:italic>m</jats:italic>,<jats:italic>a</jats:italic>= 4.29142(4),<jats:italic>c</jats:italic>= 38.1638(4) Å,<jats:italic>R</jats:italic><jats:sub>B</jats:sub>= 0.0344. The main feature of the structure is the statistical distribution of Sc atoms and Al<jats:sub>3</jats:sub>triangles within atomic layers of composition Sc<jats:sub>2</jats:sub>Al<jats:sub>3</jats:sub>(Sc<jats:sub>0.67</jats:sub>Al within the translation unit here), which is likely to correspond to stacking disorder of ordered layers. During the final cycles of the refinement, the occupancies of the corresponding sites were fixed at occ. = 2/3 for Sc in Wyckoff position 6<jats:italic>c</jats:italic>and occ. = 1/3 for Al in 18<jats:italic>h</jats:italic>. The unit cell of Sc<jats:sub>1.33</jats:sub>Pd<jats:sub>3</jats:sub>Al<jats:sub>8</jats:sub>contains six Sc<jats:sub>0.67</jats:sub>Al layers, nine Pd and eighteen Al atom layers along the crystallographic direction [001]. Together with the structure types Tb<jats:sub>0.67</jats:sub>PdAl<jats:sub>3</jats:sub>, Y<jats:sub>2</jats:sub>Co<jats:sub>3</jats:sub>Ga<jats:sub>9</jats:sub>, Sc<jats:sub>0.67</jats:sub>Fe<jats:sub>2</jats:sub>Si<jats:sub>5</jats:sub>, Er<jats:sub>4</jats:sub>Pt<jats:sub>9</jats:sub>Al<jats:sub>24</jats:sub>, Yb<jats:sub>0.67</jats:sub>Ni<jats:sub>2</jats:sub>Al<jats:sub>6</jats:sub>, and ErNi<jats:sub>3</jats:sub>Al<jats:sub>9</jats:sub>, the structure type Gd<jats:sub>1.33</jats:sub>Pt<jats:sub>3</jats:sub>Al<jats:sub>8</jats:sub>forms a family of intergrowth structures built up of three kinds of similar monoatomic layer.</jats:p>
