Elemental Chemical Analysis

The title compound, namely octaaquaytterbium(III) aquanonachlorotricadmate(II) hexahydrate, [Yb(H2O)8][Cd3Cl9(H2O)]·6H2O, was prepared by evaporation at 278 K from an aqueous solution of the ternary system YbCl3–CdCl2–H2O and was characterized by elemental chemical analysis and by X-ray powder and single-crystal diffraction studies. The crystal structure can be viewed as being built from layers of double chains of CdCl6 and CdCl5(H2O) octahedra separated by antiprismatic [Yb(H2O)8]3+ cations. The stabilization of the structure is ensured by O—H...O and O—H...Cl hydrogen bonds. A comparison with the structures of SrCd2Cl6·8H2O and CeCd4Cl11·13H2O is presented.

A novel ligand containing sulfonic has been synthesized using 2-formylbenzenesulfonic sodium and 3-thiosemicarbazide as starting materials, and a Er (III) complex was synthesized. The ligand was characterized by element analysis and IR spectrum. The crystal structure of the Er (III) complex was determined by X-ray single crystal diffraction. The results showed that the compound was triclinic, with P-1, a = 1.0596(4) nm, b = 1.3700(5) nm, c = 1.8305(7) nm, V = 2.4726(16) nm3, Z=2, M r= 1244.42, De =1.671 g/cm3, T = 273(2) K, F (000) = 1270, R = 0.0517 and wR = 0.1124. The complex forms two-dimensional layered structure through hydrogen bonds and π-π stacking.

Abstract Red transparent single crystals of Ba9[NbN4]2O[CN2] were synthesised by the reaction of BaO coated Ba metal, C and Nb powder in arc-welded Nb ampoules at 1300 K. The title compound was characterised by X-ray single crystal diffraction (P1̅ , a = 799.05(2), b = 962.61(2) and c = 1264.38(4) pm; α = 75.859(1), β = 85.745(1) and γ = 87.8621(8)°; Z = 2) and Raman spectroscopy (νsym = 1234 and δ = 632/658/668 cm−1). It now seems likely that a nitride-azide compound we previously reported, Ba9[NbN4]2N[N3], does not exist, but is in fact the title compound.

AbstractIn the frame of the studies on the phase relations in the ternary system Li–Sb–Sn at 300 °C the new ternary phase Li8SbxSn3-x (0.3 ≤ x ≤ 1.0) was synthesized and characterized predominantly by single crystal and powder X-ray diffraction. The title compound crystallizes trigonally in the space group R$‾{3}$m (no. 166), the lattice parameters are a = 4.6962(11) Å and c = 31.536(6) Å. The crystal structure of Li8SbxSn3-x is described in the present paper. In addition, the stereochemical and topological relations to the phases with similar composition, namely Li13Sn5, Li5Sn2 as well as cubic Li3Sb, besides native Li are discussed.

Accidental Degeneracy

The crystal structure of Mg(BrO3)2·6H2O twinned crystals has been determined by X-ray single crystal diffraction (Pa3̅, a = 1039.56(9) pm). The structure is isomorphic to that of M(BrO3)2·6H2O(M = Co, Ni, Cu, Zn) and Ni(ClO3)2·6H2O. The Mg(BrO3)2·6H2O structure is related to fluorite, with Mg(H2O)62+ replacing Ca2+ and BrO3- replacing F-. The water molecules are involved in nearly linear hydrogen bonds to adjacent bromate ions (νOD of matrix isolated HDO: 2458 and 2453 cm-1). The intramolecular O-H distances 96.84 and 96.90 pm have been derived from the wavenumbers of the respective OD stretches using a recently established vOD vs. rOH correlation curve. The infrared and Raman spectra show accidental degeneracy of the symmetric and the asymmetric BrO stretching modes, which is common for bromate ions with local C3v symmetry.

Abstract The structure of the title compound has been determined by X-ray crystallography. The title compound is synthesized from the elements at 600 °C. Its crystal structure, derived from powder data [3] is refined by single crystal diffractometer data. The structure is trigonal (P3̅ml, α = 684.1(1), c = 724.4(1) pm); Pd2+ cations and PS43- anions form a network with an anti-Claudetite (AS2O3) type structure. The PS4 units are distinctly distorted from ideal tetrahedral symmetry. The Pd atoms have a planar environment of 4 S atoms.

A polycrystalline sample of a new polymorph of the title compound, C8H11NO2, was produced during a variable-temperature X-ray powder diffraction study. The crystal structure was solved at 1.67 Å resolution by simulated annealing from laboratory powder data collected at 250 K. Subsequent Rietveld refinement yielded an R wp of 0.070 to 1.54 Å resolution. The structure contains two molecules in the asymmetric unit, which form a C 2 2(8) chain motif via N—H...O hydrogen bonds.
