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 crystal structure model for Sr(ClO₄)₂ anhydrate was confirmed by the bond valence method.

Crystal structure of barium perchlorate anhydrate, Ba(ClO4)2, from laboratory X-ray powder data.

Project description:The previously unknown crystal structure of barium perchlorate anhydrate, determined and refined from laboratory X-ray powder diffraction data, represents a new structure type. The title compound was obtained by heating hydrated barium perchlorate [Ba(ClO4)2·xH2O] at 423?K in vacuo for 6?h. It crystallizes in the ortho-rhom-bic space group Fddd. The asymmetric unit contains one Ba (site symmetry 222 on special position 8a), one Cl (site symmetry 2 on special position 16f) and two O sites (on general positions 32h). The structure can be described as a three-dimensional polyhedral network resulting from the corner- and edge-sharing of BaO12 polyhedra and ClO4 tetra-hedra. Each BaO12 polyhedron shares corners with eight ClO4 tetra-hedra, and edges with two ClO4 tetra-hedra. Each ClO4 tetra-hedron shares corners with four BaO12 polyhedra, and an edge with the other BaO12 polyhedron.

Sr-fresnoite determined from synchrotron X-ray powder diffraction data.

Project description:The fresnoite-type compound Sr2TiO(Si2O7), distrontium oxidotitanium disilicate, has been prepared by high-temperature solid-state synthesis. The results of a Rietveld refinement study, based on high-resolution synchrotron X-ray powder diffraction data, show that the title compound crystallizes in the space group P4bm and adopts the structure of other fresnoite-type mineral samples with general formula A2 TiO(Si2O7) (A = alkaline earth metal cation). The structure consists of titanosilicate layers composed of corner-sharing SiO4 tetra-hedra (forming Si2O7 disilicate units) and TiO5 square-based pyramids. These layers extend parallel to the ab plane and are stacked along the c axis. Layers of distorted SrO6 octa-hedra lie between the titanosilicate layers. The Sr(2+) ion, the SiO4 tetra-hedron and the bridging O atom of the disilicate unit are located on mirror planes whereas the TiO5 square-based pyramid is located on a fourfold rotation axis.

Crystal structure of trirubidium citrate from laboratory X-ray powder diffraction data and DFT comparison.

Project description:The crystal structure of trirubidium citrate, 3Rb+·C6H5O73-, has been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional techniques. The two independent Rb+ cations are seven- and eight-coordinate, with bond-valence sums of 0.99 and 0.92 valence units. The coordination polyhedra share edges and corners to form a three-dimensional framework. The only hydrogen bond is an intra-molecular one between the hy-droxy group and the central carboxyl-ate, with graph set S(5). The hydro-phobic methyl-ene groups lie in pockets in the framework.

Crystal structure of dicaesium strontium hexa-cyanidoferrate(II), Cs2Sr[Fe(CN)6], from laboratory X-ray powder data.

Project description:Ferrocyanides with general formula A I xB II y [Fe(CN)6], where A and B are cations, are thought to accept many substitutions on the A and B positions. In this communication, the synthesis and crystal structure of Cs2Sr[Fe(CN)6] are reported. The latter was obtained from K2Ba[Fe(CN)6] particles, put in contact with caesium and strontium ions. Hence, a simultaneous ion-exchange mechanism (Cs for K, Sr for Ba) occurs to yield Cs2Sr[Fe(CN)6]. The synthesis protocol shows that K2BaFe(CN)6 particles can be used for the simultaneous trapping of radioactive caesium and strontium nuclides in water streams. Cs2Sr[Fe(CN)6] adopts the cryolite structure type and is isotypic with the known compound Cs2Na[Mn(CN)6] [dicaesium sodium hexa-cyanidomanganate(III)]. The octa-hedrally coordinated Sr and Fe sites both are located on inversion centres, and the eightfold-coordinated Cs site on a general position.

Crystal structure of dirubidium hydrogen citrate from laboratory X-ray powder diffraction data and DFT comparison.

Project description:The crystal structure of dirubidium hydrogen citrate, 2Rb+·HC6H5O72-, has been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional techniques. The un-ionized carb-oxy-lic acid group forms helical chains of very strong hydrogen bonds (O?O ? 2.42?Å) along the b axis. The hy-droxy group participates in a chain of intra- and inter-molecular hydrogen bonds along the c axis. These hydrogen bonds result in corrugated hydrogen-bonded layers in the bc plane. The Rb+ cations are six-coordinate, and share edges and corners to form layers in the ab plane. The inter-layer contacts are composed of the hydro-phobic methyl-ene groups.

In the extended structure, their polyhedra share edges and corners to form a three-dimensional network. The hydro-phobic methyl-ene groups occupy channels along the b axis.

The un-ionized carb-oxy-lic acid groups form two different types of hydrogen bonds; one forms a helical chain along the c-axis, and the other is discrete. The hy-droxy group participates in both intra- and inter-molecular hydrogen bonds.
