    Description / Table of Contents: CdHgO2: An Oxomercurate related to the Crednerite StructureSingle crystals of CdHgO2 were prepared by oxygen high pressure technique (600°C, 3900 bar) and investigated by X-ray technique. It crystallizes with monoclinic symmetry, space group C2h3-C2/m; a = 5.933, b = 3.452, c = 5.875 Å, β = 91.26°; Z = 2. The Hg2+ ions show dumb-bell like coordination, Cd2+ an octahedral one. CdHgO2 shows strong relationship to the Crednerite structure. The orientation of the O—Hg—O dump-bells to the CdO6 octahedra layers is discussed with respect to related oxomercurates.
    Notes: CdHgO2 wurde mit Sauerstoff-Hochdrucktechnik (600°C, 3900 bar) einkristallin dargestellt und röntgenographisch untersucht. Es kristallisiert monoklin, Raumgruppe C2h3-C2/m mit a = 5,933, b = 3,452, c = 5,875 Å, β = 91,26° und Z = 2. Die Hg2+-Ionen zeigen eine hantelförmige, Cd2+ eine oktaedrische Koordination. CdHgO2 zeigt große Ähnlichkeit zur Crednerit-Struktur. Die Anordnung der O—Hg—O-Hanteln zu den CdO6-Oktaederschichten wird unter Bezug auf verwandte Oxomercurate diskutiert.

    Description / Table of Contents: On an Alkali Alkaline-Earth Cadmium Oxovanadate: KBaCd2(VO4)(V2O7)Single crystals of KBaCd2(VO4)(V2O7) have been prepared by crystallization from melts. X-ray investigations led to monoclinic symmetry, space group C2h5—P21/n, a = 10.359(3), b = 6.986(2), c = 15.331(3) Å, β = 94.77(2), Z = 4. The hitherto unknown compound represents a new structure type and is one of those few examples containing VO4 and V2O7 groups.
    Notes: Einkristalle von KBaCd2(VO4)(V2O7) wurden durch Kristallisation aus der Schmelze erhalten. Röntgenographische Untersuchungen führten zu monokliner Symmetrie, Raumgruppe C2h5 — P21/n, mit a = 10,359(3), b = 6,986(2), c = 15,331(3), β = 94,77(2)°, Z = 4. Die bisher unbekannte Substanz vertritt einen neuen Strukturtyp und ist eines der wenigen Beispiele mit VO4- und V2O7-Baugruppen.

    Description / Table of Contents: On a Rubidium Cadmium Oxovanadate(V) Showing a Tunnel Structure: RbCd3(VO4)(V2O7)Colourless single crystals of RbCd3(VO4)(V2O7) have been prepared by heating of RbVO3, CdO and V2O5 in closed steel tubes. It shows monoclinic symmetry, space group C2h5-P21/c, a = 8.397(2), b = 9.775(2), c = 12.616(2) Å, β = 98.50(2)°, Z = 4. Despite the similarity of the chemical composition to other oxovanadates(V) RbCd3(VO4)(V2O7) form a new structure type, characterized by a [Cd3V3O11] network made up from CdO6 octahedra, VO4 tetrahedra and V2O7 divanadate groups. Typical features are edge shared [Cd3O13] units and the edge bridging of two CdO6 octahedra by one V2O7 group.
    Notes: Farblose Einkristalle von RbCd3(VO4)(V2O7) wurden in geschlossenen Stahlampullen aus RbVO3, CdO und V2O5 dargestellt. Sie kristallisieren mit monokliner Symmetrie, Raumgruppe C2h5-P21/c, mit a = 8,397(2), b = 9,775(2), c = 12,616(2) Å, β = 98,50(2)°, Z = 4. Trotz der Ähnlichkeit der chemischen Zusammensetzung zu anderen Oxovanadaten(V) bildet RdCd3(VO4)(V2O7) einen neuen Strukturtyp, der durch ein [Cd3V3O11]-Gerüst gekennzeichnet ist, welches aus CdO6Oktaedern, VO4-Tetraedern und V2O7-Tetraederdoppeln aufgebaut ist. Charakteristika der Kristallstruktur sind kantenverknüpfte [Cd3O13]-Baugruppen und die Überbrückung zweier CdO6-Oktaederkanten durch eine V2O7-Gruppe.

    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.

    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.
