    Description / Table of Contents: On BaCdGeS4 and the Crystal Chemistry of the BaABS4-Type CompoundsBaCdGeS4 was prepared for the first time and investigated by using X-ray methods. It crystallizes isotypically with BaCdSnS4 [1]. Space group C2v19-Fdd2 (No. 43). Lattice constants: a = 2169, b = 2125, c = 1278 pm. The structure is formed by the characteristically linked edge sharing “double-tetrahedrons”. The topological linkage of the tetrahedrons is compared with other related structures and discussed in respect of the nature of the metal-sulfur bond.
    Notes: BaCdGeS4 wurde erstmals dargestellt und röntgenographisch untersucht. Es kristallisiert isotyp mit BaCdSnS4 [1] in der Raumgruppe C2v19-Fdd2 (Nr. 43). Gitterkonstanten: a = 2169, b = 2125, c = 1278 pm. Die charakteristisch verknüpften „Doppeltetraeder“ mit gemeinsamen Kanten bilden das strukturbestimmende Tetraedergerüst. Die topologische Verknüpfung d er Tetraeder wird mit verwandten Strukturen verglichen und in bezug auf den Bindungscharakter der Metall-Schwefel-Bindung diskutiert.

    Description / Table of Contents: Determination of the Phase Width of Zinc OxideThe homogeneity range of zinc oxide was determined coulometrically by oxydation of non-stoichiometric samples in a gas-solid-phase-reaction using a solid electrolyte cell. Single crystals with the composition according to the lower phase boundary were prepared by chemical transport reaction. The deviation of the lower phase boundary from the stoichiometric composition depends upon the temperature amounting to 30-240 ppm in the region 800-1100°C.
    Notes: Das Homogenitätsgebiet von Zinkoxid wurde durch Oxydation unterstöchiometrischer Proben in einer Gas-Festreaktion mit einer Festelektrolytzelle coulometrisch bestimmt. Die Darstellung der Einkristalle der unteren Phasengrenzzusammensetzung erfolgte durch chemischen Transport. Die Abweichung von der stöchiometrischen Zusammensetzung der unteren Phasengrenze hängt von der Temperatur ab und liegt zwischen 30 und 240 ppm im Bereich von 800-1100°C.

    Description / Table of Contents: Preparation and Crystal Structure of Barium-Cadmium-Thiostannate (IV) BaCdSnS4BaCdSnS4 was prepared for the first time and the crystal structure determined by single crystal X-ray investigations. Lattice constants: a = 2186 ± 2; b = 2169 ± 1; c = 1318 ± 0.5 pm. Space group: C2v19-Fdd2. There are pairs of edge-sharing tetrahedrons linked together characteristically to form twodimensional endless nets. The crystal structure is described and discussed.
    Notes: BaCdSnS4 wurde erstmals präpariert und die Kristallstruktur an Einkristallen bestimmt.Gitterkonstanten: a = 2186 ± 2; b = 2169 ± 1; c = 1318 ± 0,5 pm. Raumgruppe C2v19-Fdd2. Die Kristallstruktur enthält Doppeltetraeder [CdSnS4]2-. Sie sind in charakteristischer Weise zu zweidimensionalen, unendlichen Netzen verknüpft. Der Aufbau der Kristallstruktur wird beschrieben und diskutiert.
