    Description / Table of Contents: The position of the Kα1,2 band in the X-ray spectra of Mg2+ in oxides and silicates is, to a minor extent, dependent on the coordination number of Mg, the Mg—O distance, and the orientation of the O2- ligands in relation to the 2p orbitals of Mg.There is a splitting of the Kβ band of Mg for four- and six-coordination; no splitting occurs for the case of eight-coordination. There is evidence that in the [MgO4] and [MgO6] polyhedra some of the πb orbitals, derived from the 3b terms, are at lower energetic position than the πb orbitals, derived from the 3p terms.
    Notes: Die Lage der Kα1,2-Bande von Mg2+ in Oxiden und Silicaten ist in geringem Maße abhängig von der Koordinationszahl, von dem Mg—O-Abstand und der Orientierung der O2--Liganden in Bezug auf die Mg 2p-Orbitale.Die Mg Kβ-Bande zeigt bei 4- und 6-Koordination eine Aufspaltung. Bei 8-Koordination tritt keine Aufspaltung auf. Mit Hilfe der molecular-orbital-Theorie läßt sich eine Zuordnung der Teilbanden treffen. Es ergeben sich Hinweise darauf, daß im [MgO4]- und [MgO6]-Polyeder einige der aus den 3d-Zuständen hervorgegangenen πb-Orbitale energetisch tiefer liegen als die πb-Orbitale aus den 3p-Zuständen.

    Description / Table of Contents: The reduction of WO3. H2O and WO3. 2 H2O by means of zinc and HCl leads to blue oxide hydrates, which are very sensitive to air. The lowest degree of reduction being achieved is 2.65. By thermal decomposition one obtains blue oxides, the structures of which can be deduced from WO3. With increasing degree of reduction the pseudo-orthorhombic WO3 cell becomes tetragonal and finally cubic (ReO3 type). There exists a close relationship to the reduced tungsten oxide hydroxides WO3-X(OH)X with x → 0.5.
    Notes: Die Reduktion von WO3. H2O und WO3. 2 H2O mit Zink und Salzsäure führt zu blauen, sehr luftempfindlichen Oxidhydraten. Der niedrigste erreichte Reduktionsgrad beträgt 2,65. Durch isobaren Abbau erhält man daraus wasserfreie Wolframblauoxide, deren Strukturen sich von WO3 ableiten lassen. Mit zunehmendem Reduktionsgrad wird die pseudo-orthorhombische WO3-Zelle tetragonal und schließlich kubisch (ReO3-Typ). Es bestehen Analogien zu den reduzierten Wolframoxidhydroxiden WO3-X(OH)X mit x → 0,5.
