    Description / Table of Contents: A new Alkaline-Alkaline-Earth-Copper-Oxovanadate: Kba3Ca4Cu3V7O28.Single crystals of Kba3Ca4Cu3V7O28 were prepared by solid state reactions below the melting point of the reaction mixture. It crystallizes with hexagonal symmetry, space group C6v4-P63mc, a=11.160, c=12.428 Å, Z=2. Kba3Ca4Cu3V7O28 represents a new structure type with special coordination polyhedra around Ba2+, trigonal prisms and octahedra around Ca2+ and Cu2+ inside square pyramids. The crystal structure will be shown and discussed.
    Notes: Einkristalle von Kba3Ca4Cu3V7O28 wurden durch Feststoffreaktionen, knapp unterhalb des Schmelzpunktes, erhalten. Die Verbindung kristallisiert hexagonal, Raumgruppe C6v4-P63mc, a=11,160, c=12,428 Å, Z=2. Kba3Ca4Cu3V7O28 repräsentiert einen neuen Strukturtyp, mit speziellen Koordinationspolyedern um Ba2+, trigonalen Prismen und Oktaedern um Ca2+ und Cu2+ in tetragonal pyramidaler Koordination. Die Kristallstruktur wird vorgestellt und diskutiert.

    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 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.

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: Cadmium in Square Pyramids of Oxygen in the Barium Cadmium Oxovanadate: Ba2Cd3(VO4)2(V2O7)Single crystals of Ba2Cd3(VO4)2(V2O7) have been prepared by crystallization of a melt of BaCO3, CdO and V2O5. It shows orthorhombic symmetry, space group D42—P212121, a = 7.206(2), b = 9.978(1), c = 19.617(3) Å, Z = 4. The crystal structure is characterized by (VO4)3- and (V2O7)4- groups, CdO6 octahedra, BaO12 and BaO9 polyhedra and with respect to Cd containing oxides unusual square pyramids of O2- around Cd2+. The observed 1∞[CdO4] zickzack chains are connected by VO4 tetrahedra, V2O7 double tetrahedra and CdO5 pyramids, forming a tunnel structure along [100]. The tunnels are filled by barium.
    Notes: Einkristalle von Ba2Cd3(VO4)2(V2O7) wurden durch Kristallisation aus einer Schmelze von BaCO3, CdO und V2O5 dargestellt. Sie zeigen orthorhombische Symmetrie, Raumgruppe D42—P212121 mit a = 7,206(2), b = 9,978(1), c = 19,617(3) Å, Z = 4. Die Kristallstruktur zeichnet sich durch VO4-Tetraeder, V2O7-Tetraederdoppel, CdO6-Oktaeder, BaO12- und BaO9-Polyeder und für Cd unübliche tetragonale Pyramiden aus. Die beobachteten 1∞[CdO4]-Zick-zack-Ketten werden durch VO4-Tetraeder, V2O7-Tetraederdoppel und CdO5-Pyramiden unter Ausbildung einer längs [100] orientierten Tunnelstruktur vernetzt. Die Tunnel sind mit Ba2+ aufgefüllt.
