Abstract

The crystal structure of strontium perchlorate anhydrate, Sr(ClO ₄ ) ₂ , was determined and refined from laboratory powder X-ray diffraction data. The material was obtained by dehydration of Sr(ClO ₄ ) ₂ 3H ₂ O at 523 K for two weeks. It crystallizes in the orthorhombic space group Pbca and is isotypic with Ca(AlD ₄ ) ₂ and Ca(ClO ₄ ) 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 Sr ²⁺ cations and isolated ClO4+ tetrahedra. The Sr ²⁺ cation is coordinated by eight O atoms from eight ClO4+ tetrahedra. The validity of the crystal structure model for Sr(ClO4)2 anhydrate was confirmed by the bond valence method.
