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 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...
متن کاملCrystal structure of a new monoclinic polymorph of N-(4-methylphenyl)-3-nitropyridin-2-amine
The title compound, C12H11N3O2, is a second monoclinic polymorph (P21, with Z' = 4) of the previously reported monoclinic (P21/c, with Z' = 2) form [Akhmad Aznan et al. (2010 ▶). Acta Cryst. E66, o2400]. Four independent mol-ecules comprise the asymmetric unit, which have the common features of a syn disposition of the pyridine N atom and the toluene ring, and an intra-molecular amine-nitro N-H...
متن کاملCrystal structure of a monoclinic polymorph of 5-amino-1,3,4-thiadiazol-2(3H)-one
The title compound, C2H3N3OS, is a monoclinic (P21/c) polymorph of the previously reported triclinic structure [Kang et al. (2012 ▶). Acta Cryst. E68, o1198]. The asymmetric unit contains two independent mol-ecules which are essentially planar, with r.m.s. deviations of 0.001 and 0.032 Å from the mean plane defined by the seven non-H atoms. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds link th...
