    Description / Table of Contents: Zusammenfassung.  Schiffsche Basen von Acetylaceton, Benzoylaceton, Dibenzoylmethan und Thienoyltrifluoroaceton mit Ethanolamin und 2-Aminophenol wurden hergestellt und mittels Elementaranalyse, IR-Spektroskopie und 1H-NMR-Spektroskopie charakterisiert. Die Dissoziationskonstanten wurden in Ethanol-Wasser bei einer lonenstärke von 0.1 M KNO3 bei verschiedenen Temperaturen bestimmt; die entsprechenden thermodynamischen Größen wurden berechnet. Das Röntgendiffraktionsmuster eines Einkristalls einer der Verbindungen wurde analysiert. Thermische Untersuchungen wurden durchgeführt und die Ergebnisse mit den Strukturen korreliert.
    Notes: Summary.  Schiff bases of acetylacetone, benzoylacetone, dibenzoylmethane, and thienoyltrifluoroacetone with ethanolamine and 2-aminophenol were synthesized and characterized by elemental analysis, infrared and 1H NMR spectra. Dissociation constants of the synthesized ligands were determined in methanol-water and at an ionic strength of 0.1 M KNO3 at different temperatures; the associated thermodynamic parameters were calculated. Single crystals of one of the ligands were prepared; the X-ray diffraction pattern was analyzed. Thermal analyses of the investigated ligands were performed and correlated with the ligand structure.

CoSO4 and Pyrazine crystallize in a polymeric (I) as well as in a dimeric (II) compound. In the polymeric compound the molecules are bonded by pyrazine to form alternating linear chains. The dimer is a dinuclear complex with a bridging pyrazine molecule.

    Crystal growth and conductivity investigations on BiVO4 single crystals (1996)

    Notes: Abstract Some oxides with the scheelite structure are well known mixed ionic and electronic conductors. This structure family, with the general composition ABO4, can be described as a layer structure derivative of the fluorite structure. The relations between the structural and the electrical transport properties of these materials have been investigated. The model system used in this work was BiVO4, which shows both electronic and ionic conduction. Single crystals of bismuth vanadate (BiVO4) were grown using the Czochralski technique. Single crystal boules up to 55 mm in diameter and up to 30 mm long were produced. The crystallographic orientation was determined by the Laue method, and they were cleaved along [001] planes and polished to optically perfect cubes with an edge length of 5 mm. Two-point ac impedance measurements in the temperature range between 550°C and 700°C were performed. The conductivities were measured as a function of the crystal orientation and showed strong anisotropy as expected from the crystal structure.
