Crystal structure of strontium perchlorate anhydrate, Sr(ClO₄)₂, from laboratory powder X-ray diffraction data.

ABSTRACT: The crystal structure of strontium perchlorate anhydrate, Sr(ClO₄)₂, was determined and refined from laboratory powder X-ray diffraction data. The material was obtained by dehydration of Sr(ClO₄)₂·3H₂O at 523 K for two weeks. It crystallizes in the ortho-rhom-bic space group Pbca and is isotypic with Ca(AlD₄)₂ and Ca(ClO₄)₂. The asymmetric unit contains one Sr, two Cl and eight O sites, all on general positions (Wyckoff position 8c). The crystal structure consists of Sr²⁺ cations and isolated ClO₄ ^- tetra-hedra. The Sr²⁺ cation is coordinated by eight O atoms from eight ClO₄ ^- tetra-hedra. The validity of the crys
