We characterize experimentally and theoretically the promising new solid oxide fuel cell electrode material Sr(2)Fe(1.5)Mo(0.5)O(6-δ) (SFMO). Rietveld refinement of powder neutron diffraction data has determined that the crystal structure of this material is distorted from the ideal cubic simple perovskite, instead belonging to the orthorhombic space group… (More)
Single crystals of tetracalcium iridium hexaoxide, Ca(4)IrO(6), tricalcium magnesium iridium hexaoxide, Ca(3)MgIrO(6), and tricalcium zinc iridium hexaoxide, Ca(3)ZnIrO(6), were prepared via high-temperature flux growth and structurally characterized by single-crystal X-ray diffraction. The three compounds are isostructural and adopt the K(4)CdCl(6)… (More)
Single crystals of Ba9Rh8O24, grown from a molten potassium carbonate flux, crystallize in the spacegroup R3c with lattice parameters of a = 10.0899(4) and c = 41.462(2) A. Magnetic measurements on oriented single crystals reveal the existence of magnetic anisotropy.
In the title compound, [Zn(C(6)H(3)FNO(2))(2)(H(2)O)(4)]·2H(2)O, the Zn(II) atom is octa-hedrally coordinated in a ZnO(4)N(2) environment by two 3-fluoro-pyridine-4-carboxyl-ate (3-fpy4-cbx) ligands and four water mol-ecules. The [Zn(3-fpy4-cbx)(2)(H(2)O)(4)] mol-ecules form a three-dimensional network through strong O-H⋯O and weak O-H⋯F hydrogen bonds… (More)
The title compound, [Zn(C(7)H(4)FO(3))(2)(H(2)O)(2)], is a monomeric Zn(II) complex. The Zn(II) atom, which lies on a twofold rotation axis, is situated in a distorted tetra-hedral environment composed of two monodentate carboxlyate O atoms and two water O atoms. O-H⋯O hydrogen bonds link these units, forming sheets that are stacked along the c axis.
