    Description / Table of Contents: The Crystal Structure of KPdMIVF7 (MIV = Zr, Hf)Blue single crystals of KPdZrF7 are obtained by heating the binary fluorides in sealed Pt-tubes under dry argon (solid state reaction, T ≍ 720°C, t ≍ 14 d). The compound crystallizes orthorhombically in the space group Pnna-D2h6 (Nr. 52); lattice parameters are a = 1 132.3(5) pm, b = 797.5(2) pm, c = 639.8(1) pm; Z = 4 (Four cycle diffractometer data, AED2). According to [F4PdF2/1ZrF5] distortet [PdF6]-octaedra are connected with pentagonal-bipyramidal [ZrF7]-polyhedra via two bridging F-, resulting in [PdZrF11]-groups. These [PdZrF11]-groups built up a threedimensional-network with K+ in its spacings. KPdHfF7 crystallizes isotypically (a = 1 136.1(3) pm, b = 796.4(2) pm und c = 638.8(1) pm; four cycle diffractometer data, AED2).
    Notes: Durch Tempern der binären Fluoride im verschweißten Pt-Rohr unter Schutzgas (Ar, Festkörperreaktion, T ≍ 720°C, t ≍ 14d) erhält man blaue Einkristalle von KPdZrF7 [eigener Strukturtyp, orthorhombisch, Pnna-D2h6 (Nr. 52); a = 1 132,3(5) pm, b = 797,5(2) pm, c = 639,8(1) pm; Z = 4; Vierkreisdiffraktometerdaten AED2]. Pd2+ ist verzerrt oktaedrisch von 6 F- umgeben, wohingegen Zr4+ pentagonalbipyramidal von 7 F- koordiniert wird. Beide Koordinationspolyeder sind gemäß [F4PdF2/1ZrF5] kantenverknüpft und bilden mit weiteren solcher [PdZrF11]-Einheiten durch Eckenverknüpfung ein dreidimensionales Raumnetz, in dessen Lücken K+ eingelagert ist. Nach Vierkreisdiffraktometerdaten (AED2) kristallisiert KPdHfF7 isotyp (a = 1 136,1(3) pm, b = 796,4(2) pm und c = 638,8(1) pm).

    Description / Table of Contents: Cs2Cu3MIVF12 (MIV = Zr, Hf) - Crystal Structure and Magnetic BehaviourColourless single crystals of Cs2Cu3ZrF12 are obtained by heating the binary fluorides in sealed Pt-tubes under dry argon (solid state reaction, T ≍ 700°C, t ≍ 7-10 d). The compound crystallizes trigonal-rhomboedrical in the space group R3m-D3d5 (Nr. 166); lattice parameters are a = 716.61(6) pm, c = 2 046.4(2) pm, Z = 3 (Four cycle diffractometer data, AED 2). The structure is dominated by layers of corner-sharing, Jahn-Teller-distorted [CuF6]-Octahedra, which are connected via regular [ZrF6]-Octahedra to stackings parallel [00.1]. Cs+-ions are located in the spacings of the octahedra-network. From powder data Cs2Cu3HfF12 with a = 716.32(4) pm, c = 2 048.6(2) pm is isotypic. Both compounds show antiferromagnetic behaviour already at temperatures about 200 K.

    The gross features of the lithosphere-asthenosphere system in Europe from seismic surface waves and body waves (1980)
    Springer
    Pure and applied geophysics 118 (1980), S. 1209-1213 
    Details
    ISSN: 1420-9136
    Keywords: Seismology ; Phase velocity dispersion ; Rayleigh waves ; ‘Hedgehog’ inversion method ; Lithosphere-asthenosphere system in Europe
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract Long-period recordings of dispersive Rayleigh waves along numerous station lines, or ‘profiles’, in Europe have for the first time permitted a uniform inversion of these observations based on a new method of phase velocity regionalization. Regional dispersion relations obtained by this method have then been subjected to a complete inversion procedure commonly known as the ‘hedgehog’ method. The results are presented in a map outlining the thickness of the lower lithosphere (‘lid’) and the shear (S) velocities in both the ‘lid’ and the asthenosphere ‘channel’. A comparison of these results with the minimum compressional (P) wave velocities in the asthenosphere and their corresponding depths provides an estimate of theV p /V s ratio for the asthenosphere in the European area.

    Notes: Abstract Diaza-18-crown-6 (1,4,10,13-tetraoxa-7,16-diaza-cyclo-octadecane) selectively precipitates as a 1,4-dihydroxybenzene-complex from a mixture of isomeric phenols and as a 2,6-dihydroxynapthalene-complex from mixtures of isomeric diols. These selective precipitations are discussed in terms of structure and solubility of the host-guest complexes and phenol acidity. The crystal structures of diaza-18-crown-6 with guestsp-nitrophenol (2: 1), 2,4-dinitroaniline (2: 1), 5,5-diethylbarbituric acid (2: 1), salicylaldoxime (2: 1) and 1,4-dihydroxybut-2-yne (1: 1) are reported.

    Description / Table of Contents: A Novel Synthetic Access to the Tungsten Bronze Cs0.29WO3 and its Crystal StructureThe hexagonal tungsten bronze Cs0.29WO3 was obtained in form of black, prismatic crystal by the reduction of WO3 with molten cesium iodide at 700°C. Its crystal structure was determined by X-ray diffraction (399 unique observed reflexions, R = 0.058). Crystal data: a = 741.2(3), c = 760.0(5) pm, space group P6322, Z = 6. It corresponds to the known structure of hexagonal tungsten bronzes, having tungsten atoms displaced from the octahedra centres by 11.9 pm and with three different W—O bond lengths (198, 191, 187 pm). The WO6 octahedra are slightly titled mutually.
    Notes: Bei der Reaktion von WO3 in einer Caesiumiodid-Schmelze bei 700°C entsteht die hexagonale Wolframbronze Cs0.29WO3 in Form schwarzer, hexagonal-prismatischer Kristalle.

Es handelt sich um die bekannte Struktur der hexagonalen Wolframbronzen mit Wolframatomen, die aus den Oktaedermitten um 11,9 pm herausgerückt sind und mit drei verschiedenen W—O-Bindungslängen (198, 191, 187 pm).
