Crystal structure of monoclinic hydrous wadsleyite [β-(Mg,Fe)2SiO4]
Wadsleyite (β-(Mg,Fe)2SiO4) is known to accept variable amounts of H, and may be an important reservoir of H in the transition zone of the mantle. The crystal structure of Fo94.6 hydrous wadsleyite (Mg1.730Fe0.098 Al0.008Si0.991H0.355O4) synthesized at 1400 oC and 17GPa has been refined in space group I2/m from 1784 measured intensities of which 830 were unique, and of these, 650 were of intens...
متن کاملCrystal structure of 8-hydroxyquinoline: a new monoclinic polymorph
In an attempt to grow 8-hy-droxy-quinoline-acetamino-phen co-crystals from equimolar amounts of conformers in a chloro-form-ethanol solvent mixture at room temperature, the title compound, C9H7NO, was obtained. The mol-ecule is planar, with the hy-droxy H atom forming an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules form centrosymmetric dimers via two O-H⋯N hydrogen bonds. Thu...
متن کاملCrystal Structure of the Superconducting Phase of Sulfur Hydride
A superconducting critical temperature above 200 K has recently been discovered in H2S (or D2S) under high hydrostatic pressure1, 2. These measurements were interpreted in terms of a decomposition of these materials into elemental sulfur and a hydrogen-rich hydride that is responsible for the superconductivity, although direct experimental evidence for this mechanism has so far been lacking. He...
متن کاملCrystal structure studies on sulfur oxygenase reductase from Acidianus tengchongensis.
Sulfur oxygenase reductase (SOR) simultaneously catalyzes oxidation and reduction of elemental sulfur to produce sulfite, thiosulfate, and sulfide in the presence of molecular oxygen. In this study, crystal structures of wild type and mutants of SOR from Acidianus tengchongensis (SOR-AT) in two different crystal forms were determined and it was observed that 24 identical SOR monomers form a hol...
متن کاملCrystal structure of the monoclinic phase (phase IV) of bis(tetramethylammonium) tetrachloridocuprate(II)
The crystal structure of the low-temperature monoclinic phase of the title compound, [(CH3)4N]2[CuCl4], was determined at 120 K. The structure of the room-temperature phase has been determined in the ortho-rhom-bic space group Pmcm [Morosin & Lingafelter (1961 ▸). J. Phys. Chem. 50-51; Clay et al. (1975 ▸). Acta Cryst. B31 289-290]. The asymmetric unit consists of one discrete tetra-chlorido-cu...
