A new organic–inorganic hybrid material, {(C7H10NO)[BiI4]·2H2O}n, has been synthesized by slow evaporation of an aqueous solution at room temperature. The anionic sublattice of the crystal is built up by [BiI6] octahedra sharing edges. The resulting zigzag chains extend along thea-axis direction and are arranged in a distorted hexagonal rod packing. Thep-anisidinium cations and the water molecules are located in the voids of the anionic sublattice. The cations are linked to each other through N—H...O hydrogen bonds with the water molecules, and also through weaker N—H...I interactions to the anionic inorganic layers.

The title compound bis(1,4-diazoniabicyclo[2.2.2]octane) di-μ-chlorido-bis[tetrachloridobismuthate(III)] dihydrate, (C6H14N2)2[Bi2Cl10]·2H2O, was obtained by slow evaporation at room temperature of a hydrochloric aqueous solution (pH = 1) containing bismuth(III) nitrate and 1,4-diazabicyclo[2.2.2]octane (DABCO) in a 1:2 molar ratio. The structure displays a two-dimensional arrangement parallel to (100) of isolated [Bi2Cl10]4−bioctahedra (site symmetry -1) separated by layers of organic 1,4-diazoniabicyclo[2.2.2]octane dications [(DABCOH2)2+] and water molecules. O—H...Cl, N—H...O and N—H...Cl hydrogen bonds lead to additional cohesion of the structure.

The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)+cations [maximum deviations = 0.010 (3) and 0.014 (3) Å] that are nearly perpendicular to each other [dihedral angle = 84.12 (7)°]. They are bonded through N—H...Cl hydrogen bonds to distorted [CoCl4]2−tetrahedra, leading to the formation of undulating layers parallel to (100). The structure is isotypic with the Zn analogue [Kefiet. al(2011).Acta Cryst.E67, m355–m356.]

During the investigation of the Ga3+–HCl–cucurbituril system, we prepared crystals of the title compound, tetrakis(hydroxonium) bis(tetrachlorogallate) dichloride cucurbituril decahydrate, by slow evaporation of an aqueous hydrochloric solution containing Ga3+and cucurbituril at room temperature in air. The compound appeared to be isostructural with the cucurbituril tetrachloroferrate(III) adduct. The structure contains H7O3+cations, [GaCl4]−anions, cucurbituril and water molecules. The centres of the cucurbituril molecules are arranged as body-centered packing and [GaCl4]−anions are situated in space between them. There is a complicated network of hydrogen bonds in the structure.

The IR-spectrum of gypsum (CaSO4·2 H2O) in the frequency range from 10 000 to 1200 cm-1 has been investigated with polarized light at room temperature. Between 3700 and 1200 cm-1, the measurements confirm the data of HASS and SUTHERLAND and as well as those of SCHAAK derived from IR and reflection measurements. The IR-spectrum shows a great number of bands, most of which can be assigned to combination and fundamental vibrations in terms of normal vibrations of the water molecules and the sulfate ions. The influence of the lattice vibrations is briefly discussed. The existence of hydrogen bonds between the water molecules and the sulfate ions gives rise to combinations of fundamental vibrations of both complexes.

Colourless triclinic single crystals of Na6[TeMo6O24] · 22 H2O were grown from aqueous solution (space group P 1, a = 1030.89(9), b = 1056.7(1), c = 1106.32(9) pm, α = 90.120(7), β = 115.220(6), γ = 105.195(7), Ζ = 1, 295 Κ, 336 parameters, 3181 reflections, Rg = 0.0186). There are three crystallographically independent Na+ cations. Two of them are coordinated octahedrally by water molecules only. The third Na+ cation is bound to five H2O and one oxygen atom (O(4)) belonging to the Anderson-Evans type anion [TeMo6O24]6-. The sodium-centered coordination octahedra are linked by common edges exclusively formed by water molecules to yield chain-like polycations {Na3(H2O)11}n,3n+ which are bound by the Na(1)-O(4) contact to the anions situated on crystallographic centers of inversion forming a layer-like arrangement. Further connections between the polycations and the [TeMo6O24]6- anions are established by hydrogen bonds involving all the oxygen atoms of the anion except O(4) as almost equivalent proton acceptors regardless of their bonding mode to Te or Mo.

The Magnetic Field

Using neodymium ring magnets (0.5–0.65 T), the experiments on the magnetic field (MF) effects on water evaporation rate and surface tension were performed at room temperature (22–24 °C). In accordance with the literature data, the enhanced evaporation rates were observed in the experiments conducted in a period of several days or weeks. However, the evaporated amounts of water (up to 440 mg over 150 min) in particular experiments differed. The evaporated amounts depended partially on which pole of the ring magnet was directed up. The relatively strong MF (0.65 T) caused a slight decrease in surface tension (−2.11 mN/m) which lasted longer than 60 min and the memory effect vanished slowly. The surface tension data reduced by the MF action are reported in the literature, although contrary results can be also found. The observed effects can be explained based on literature data of molecular simulations and the suggestion that MF affects the hydrogen bonds of intra- and inter-clusters of water molecules, possibly even causing breakage some of them. The Lorentz force influence is also considered. These mechanisms are discussed in the paper.

(NH4)3RhCl6 · H2O is obtained in form of deep red needles by slow evaporation of an aqueous solution of RhCI3 and excess NH4Cl. It crystallizes in the orthorhombic space group Pnma with lattice constants a = 1219.3. b = 700.7, c = 1416.7 and Z = 4. The structure is built up by octahedral RhCl63- anions and NH4+ cations. The water molecules form hydrogen bridges with NH4+ cations. The reaction of (NH4)3RhCl6 with Ag+ yields Ag2[RhCl5(H2O)] and AgCl.
