Strontium tetrafluoridoborate and barium tetrafluoridoborate

T. Bunic, G. Tavcar, E. Goreshnik and B. Zemva

Synopsis: In Sr(BF₄)₂, which is isomorphous with the previously published Ca(BF₄)₂, the metal atom is eight-coordinated with a square-antiprismatic environment. Each tetrafluoridoborate anion is bonded to four metal centers. In the barium derivative, the metal center, with symmetry 2/m, is surrounded by 14 F atoms. The B atom and two of the three independent F atoms occupy special positions with symmetry m. Each anion is connected to five Ba atoms.

Formula: Ba(BF₄)₂ and Sr(BF₄)₂

Calcium chloride rhenate(VII) dihydrate

U. Jarek, M. Holynska, K. Slepokura and T. Lis

Synopsis: In the nearly tetrahedral rhenate(VII) anion of calcium chloride rhenate(VII) dihydrate, all constituent atoms lie on special positions of m2m (Re) and m (O) site symmetries. The Cl^- anion and water O atom lie on special positions of m2m and 2 site symmetry, respectively. The Ca²⁺ ion, also on a special position (m2m), is eight-coordinated in a distorted square-antiprismatic coordination mode. The crystal has a layered structure stabilized by Ca-O coordination bonds as well as O-HCl hydrogen bonds.

Formula: CaCl(ReO₄)·2H₂O
