    Description / Table of Contents: On an Oxide Chloride of CoIII: Sr8Co6O15Cl4Sr8Co6O15Cl4 was prepared for the first time by flux reaction. It crystallizes with tetragonal symmetry: space group D4h17-I4/mmm; a = 3.927; c = 31.429 Å; Z = 1. Co3+ has different coordinations. One point position show CoO6 octahedra, the other one has a CoO5Cl surrounding. An oxygen deficit exhibit partly distorted square pyramids. Sr8Co6O15Cl4 is strongly related to Ba8In6O17.5 or can be seen as Sr4Co3O7.5Cl2 as a variety of the Sr4Ti3O10 type.
    Notes: Sr8Co6O15Cl4 wurde erstmals mit einer Schmelzmitteltechnik dargestellt. Es kristallisiert tetragonal: Raumgruppe D4h17-I4/mmm; a = 3,927; c = 31,429 Å; Z = 1. Co3+ ist unterschiedlich koordiniert. Eine Punktlage weist eine oktaedrische CoO6-, die zweite eine CoO5Cl-Umgebung auf. Bedingt durch ein Sauerstoffdefizit treten im Mikrobereich tetragonale CoO5-Pyramiden auf. Sr8Co6O15Cl4 ist eng mit Ba8In3O17,5 verwandt, oder kann in der Schreibweise Sr4Co3O7,5Cl2 als Variante des Sr4Ti3O10-Typs angesehen werden.

    Description / Table of Contents: On a Second Alkaline Earth-Copper Oxovanadate: SrCuV2O7Single crystals of SrCuV2O7 were prepared by solid state reaction in the order of the meltingpoint of the component mixture. The yellowgreen crystals have orthorhombic symmetry, space group D2h16-Pnma; a = 14.470; b = 5.470; c = 7.420 Å; Z = 4. SrCuV2O7 represent a new crystal structure with V5+ in tetrahedric coordination, forming V2O7-double-tetrahedra, which are connected with CuO5 square pyramids into planes. Sr2+ between these planes has a complicated surrounding of 11 O2-. The structure is discussed with respect to the not isotypic compound CaCuV2O7.
    Notes: Einkristalle von SrCuV2O7 wurden durch Feststoffreaktion im Bereich des Schmelzpunktes der Reaktionsmischung erhalten. Die gelbgrünen Kristalle haben orthorhombische Symmetrie, Raumgruppe D2h16-Pnma; a = 14,470; b = 5,470; c = 7,420 Å; Z = 4. SrCuV2O7 repräsentiert eine neue Kristallstruktur, die V5+ in tetraedrischer Koordination zeigt. Es treten isolierte V2O7-Tetraederdoppel auf, die mit CuO5-Pyramiden in Ebenen verknüpft sind. Sr2+ hat eine komplizierte Umgebung von 11 O2-. Die Struktur wird mit der nicht isotypen Verbindung CaCuV2O7 diskutiert.

    Description / Table of Contents: On BaTiVO4 and SrTiVO4BaTiVO4 and SrTiVO4 were prepared in closed systems by solid state reactions. They crystallize with orthorhombic symmetry (BaTiVO4: space group D2h16-Pmnb; a = 5.889; b = 7.889; c =10.397 Å; Z = 4; SrTiVO4: space group D24-P21,21,21,21; a = 5.855; b = 7.572; c = 10.012 Å; Z = 4) and belong to β-K2SO4-type. The ordered occupation of point positions by Ba2+ and Tl+ as well as the decrease in symmetry of SrTiVO4 are discussed.
    Notes: BaTiVO4 und SrTiVO4 wurden durch Festkörperreaktionen im geschlossenen System dargestellt. Beide Verbindungen Kristallisieren orthorhombisch (BaTiVO4: Raumgruppe D2h16-Pmnb; a = 5,889; b = 7, 889; c = 10,397; Å; SrTiVO4: Raumgruppe D24-P21,21,21,; a= 5,855; b = 7,572; c = 10,012 Å; Z = 4) und stellen Varianten des β-K2SO4-typs dar. Die geordnete Besetzung der Punktlagen mit Ba2+ und Tl+ sowie die Symmetrieerniedrigung in SrTiVO4 werden diskutiert.
