    Description / Table of Contents: On the Crystal Structure of CuInMo2O8.Single crystals of CuInMo2O8 were prepared and investigated by X-ray work. It shows monoclinic symmetry, space group C62h - C2/c; a = 9.549 Å, b = 11.529 Å, c = 5.000 Å; β = 91.38(2)°, Z = 4. CuInMo2O8 represents a LiYbW2O8 related structure, characterised by zigzag-chains of MoO6-octahedrons and octahedrons around copper and indium. With respect to LiFeW2O8 the single and three-valent ions are in opposite distribution. There are strong evidence for molybdenum in lowered oxidation state.
    Notes: CuInMo2O8 wurde synthetisiert und Einkristalle röntgenographisch untersucht. Es kristallisiert monoklin, Raumgruppe C62h - C2/c, mit a = 9,549 Å, b = 11,529 Å, c = 5,000 Å; β = 91,38(2)°; Z = 4. CuInMo2O8 ist im Aufbau mit LiFeW2O8 eng verwandt. Beide sind durch Zickzack-Ketten aus MO6-Oktaedern (M=Mo, W) sowie Oktaedern von O2- um Kupfer und Indium charakterisiert. Im Hinblick auf LiFeW2O8 sind ein- und dreiwertige Ionen vertauscht. Es gibt Hinweise für Molybdän in erniedrigter Oxidationszahl.

    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: A Contribution on the Crystal Structure of CuSmMo2O8 and CuGdMo2O8Single crystals of (I) CuSmMo2O8 and (II) CuGdMo2O8 were prepared and investigated using an X-ray technique. Both compounds crystallize with orthorhombic symmetry, space group D2h15-Pbca with Z = 8. ((I): a = 10.302, b = 9.796, c = 14.697 Å; (II): a = 10.200, b = 9.779, c = 14.646 Å). The crystal structure and the classification into the already known Copper(I) Lanthanoidemolybdates are discussed.
