    Description / Table of Contents: Mesoperiodates M3IO5 of Rubidium and CaesiumMesoperiodates M3IO5 of rubidium and caesium were prepared by solid state reactions from metaperiodates MIO4 and alkali hyperoxides. From X-ray powder data, the alkali and iodine positions were found to agree with an orthorhombic variant of the (NH4)3FeF6 structure, probably with pyramidal IO5 groups in the place of FeF6 octahedra. Cs3ReO5 is an isostructural compound.
    Notes: Mesoperjodate M3JO5 des Rubidiums und Caesiums wurden durch Festkörperreaktionen aus Metaperjodaten MJO4 und Alkalihyperoxiden dargestellt. Den Röntgenpulverdaten zufolge entspricht die Lage der Alkali- und Jodatome einer orthorhombisch verzerrten (NH4)3FeF6-Struktur, wobei wahrscheinlich pyramidale JO5-Gruppen an die Stelle der FeF6-Komplexe treten. Mit gleicher Struktur kristallisiert auch Cs3ReO5.

    Description / Table of Contents: Crystal Structure of Li8PbO6The crystal structure of Li8PbO6 (Li8TbO6 structure, space group R3—C3i2, hexagonal lattice constants a = 554.3, c = 1 563 pm) has been refined by profile analysis of a neutron diffraction pattern. Deviations from ideal tetrahedral and octahedral coordination of lithium atoms are similar to those described for Li8SnO6.
    Notes: Die Kristallstruktur von Li8PbO6 (Li8TbO6-Typ, Raumgruppe R3—C3i2, hexagonale Gitterkonstanten a = 554,3, c = 1 563 pm) wurde durch Profilanalyse einer Neutronen-Pulveraufnahme verfeinert. Die Koordinationen der Lithiumatome zeigen ähnliche Abweichungen von der idealen tetraedrischen bzw. oktaedrischen Geometrie, wie sie für Li8SnO6 beschrieben worden sind.

    Description / Table of Contents: The Crystal Structure of K3IO5The crystal structure of K3IO5, tetragonal, space group P4/ncc-D4h8, was determined by X-ray and neutron powder diffraction. It is closely related to that of (NH4)3FeF6, with a tetragonally deformed unit cell, the c lattice constant being twice as large as that of the fluorine compound, and with tetragonal IO5 pyramids replacing the octahedral FeF6 complexes.
    Notes: Die Kristallstruktur von K3JO5, tetragonal, Raumgruppe P4/ncc-D4h8, wurde durch Röntgen- und Neutronenbeugungsversuche an Pulverpräparaten bestimmt. Sie ist eng verwandt mit der von (NH4)3FeF6, wobei unter tetragonaler Verzerrung und Verdoppelung der c-Gitterkonstante die FeF6-Komplexe durch tetragonal-pyramidale JO5-Gruppen ersetzt sind.

    Description / Table of Contents: The Crystal Structure of MgTe2O5The crystal structure of MgTe2O5, orthorhombic, space group Pbcn-D2h14, contains Te2O5 groups in which Te(IV) is surrounded by three oxygen atoms in a pyramidal arrangement, and one oxygen is common to both tellurium atoms. By longer Te—O bonds, these Te2O5 groups are linked together into chains. MnTe2O5 crystallizes with the same structure, in which the bivalent metal is octahedrally coorkinated.
    Notes: Die Kristallstruktur von MgTe2O5, orthorhombisch, Raumgruppe Pbcn-D2h14, enthält Te2O5 -Gruppen, in denen Te(IV) von drei Sauerstoffatomen in pyramidaler Anordnung koordiniert und ein Sauerstoffatom beiden Telluratomen gemeinsam ist. Durch längere Te—O-Bindungen sind diese Te2O5-Gruppen kettenartig verknüpft. Mit der gleichen Struktur, in der das zweiwertige Metall oktaedrisch koordiniert ist, kristallisiert auch MnTe2O5.
