Abstract
<jats:p>Sr<jats:sub>8</jats:sub>[Al<jats:sub>12</jats:sub>O<jats:sub>24</jats:sub>](SO<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>(SAS) and Ca<jats:sub>8</jats:sub>[Al<jats:sub>12</jats:sub>O<jats:sub>24</jats:sub>](SO<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>(CAS) are members of the aluminate sodalite-type oxides with the general chemical formula<jats:italic>M</jats:italic><jats:sub>8</jats:sub>[Al<jats:sub>12</jats:sub>O<jats:sub>24</jats:sub>](<jats:italic>X</jats:italic>O<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>(<jats:italic>M</jats:italic><jats:sup>2+</jats:sup>is the guest cation and<jats:italic>X</jats:italic>O<jats:sub>4</jats:sub><jats:sup>2−</jats:sup>is the guest anion). To discuss the role of the guest cations (<jats:italic>M</jats:italic><jats:sup>2+</jats:sup>= Sr<jats:sup>2+</jats:sup>and Ca<jats:sup>2+</jats:sup>) on the rotation of AlO<jats:sub>4</jats:sub>in the oxygen tetrahedral framework in the<jats:italic>I</jats:italic><jats:overline>4</jats:overline>3<jats:italic>m</jats:italic>phase, the crystal structure parameters and the probability density function of the guest ions in SAS and CAS have been investigated<jats:italic>via</jats:italic>synchrotron radiation X-ray powder diffraction by considering Gram–Charlier expansions. The interatomic distances between the<jats:italic>M</jats:italic><jats:sup>2+</jats:sup>and O<jats:sup>2−</jats:sup>ions evaluated from the maximum positions in the probability density distribution are almost equal to the sum of the ideal ionic radii of the<jats:italic>M</jats:italic><jats:sup>2+</jats:sup>and O<jats:sup>2−</jats:sup>ions. This result suggests that the geometry of the AlO<jats:sub>4</jats:sub>tetrahedral framework and the fluctuation of the guest ions are mainly caused by steric effects between the<jats:italic>M</jats:italic><jats:sup>2+</jats:sup>and O<jats:sup>2−</jats:sup>ions.</jats:p>
