abstract = "Crystals of two new alkaline-earth perrhenate halides, Sr(ReO4)Br & sdot;2H2O (1) and Ba(ReO4)I & sdot;2H2O (2) were obtained upon evaporation of aqueous solutions at 95 - 100 degrees C. Both compounds are isostructural to the previously reported Ca(ReO4)Cl & sdot;2H2O and crystallize in orthorhombic symmetry with the space group Cmcm (a = 7.3906(5) & Aring;, b = 14.241(1) & Aring;, c = 7.1032(5) & Aring; for 1and a = 7.8624(4) & Aring;, b = 14.0202(5) & Aring;, c = 7.7190(3) & Aring; for 2). Both structures can be regarded as pseudo-layered 3D frameworks comprised of AO8X capped square antiprisms (A = Sr, Ba; X = Br, I) and ReO4 tetrahedra which share vertices with formation of slightly distorted tetragonal pseudo-layers linked by OH & sdot;& sdot;& sdot;X hydrogen bonds. The cationic centers (alkaline earths and rhenium) adopt a litharge-like arrangement. The structure seems to be very sensitive to the ratio of A2+ and X- constituents; it is as yet observed with calcium, only as a chloride, with strontium, only as a bromide, and with barium, only as an iodide",
