    Description / Table of Contents: Synthesis and Structure of a New form of CuYMo2O8Single crystals of a new form of CuYMo2O8 were prepared and investigated by X-ray diffractometer technique [space group D2h15-Pbca; a = 10.160 Å, b = 9.701 Å, c = 14.527 Å; Z = 8]. CuYMo2O8 represents a new structure type characterised by MoO4-tetrahedrons, Cu+ with coordination number 2 + 1 and square antiprisms around Y3+. The crystal structure and the Cu+ coordination are discussed.
    Notes: Einkristalle einer neuen Form von CuYMo2O8 wurden synthetisiert und mit Vierkreisdiffraktometertechnik röntgenographisch untersucht [Raumgruppe D2h15-Pbca; a = 10, 160 Å, b = 9,701 Å, c = 14, 527 Å Z = 8]. CuYMo2O8 repräsentiert einen neuen Stukturtyp mit isolierten MoO4-Tetraedern, dreifach koordiniertem Cu+ und quadratischen Antiprismen um Y3+. Die Kristallstruktur und die Koordination um Kupfer werden 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.

    Description / Table of Contents: Kristall- und Molekülstrukturen sowie Spektren zweier organischer Tetrasulfane R2S4 (R = 2-Benzothiazolyl und 4-Chlorphenyl)Bis(2-benzothiazolyl)tetrasulfan, hergestellt aus dem Mercaptan und S2Cl2, kristallisiert in der monoklinen Raumgruppe C2/c mit den im Abstract angegebenen Zelldimensionen. Die Moleküle haben C2-Symmetrie; das S4-Gerüst ist von all-trans-Konformation mit den Parametern dss = 202,7 (terminal) und 207,3 pm (zentral), αsss = 106,4° und τssss = 78,5°. Bis(4-chlorphenyl)tetrasulfan kristallisiert in der monoklinen Raumgruppe P21/a (s. Abstract). Die Moleküle befinden sich in allgemeinen Lagen, sind aber näherungsweise von C2-Symmetrie und ebenfalls von all-trans-Konformation mit dss = 203,6 (terminal), 206,7 (zentral) und 202,3 pm (terminal), αsss = 107,4° und 108,4° sowie τssss = 75,5°.

The molecules are of C2 symmetry with the geometrical parameters of the S4 backbone: dss = 202.7 (terminal) and 207.3 pm (central), αsss = 106.4°, τssss = 78.5°. The overall conformation is all-trans.Bis(4-chlorophenyl)tetrasulfane prepared from the mercaptane and diisopropoxydisulfane crystallizes in the monoclinic space group P21/a with a = 1237.7 pm, b = 748.4 pm, c = 1623.9 pm, β = 105.58°, ρ = 1.61 g cm-3 (at 298 K). The molecules occupy general positions but are approximately of C2 symmetry with dss = 203.6 (terminal), 206.7 (central) and 202.3 pm (terminal), αsss = 107.4° and 108.4°, τssss = 75.5° (all-trans conformation). The intermolecular interactions are of van der Waals type. Infrared, Raman, mass and NMR spectra (1H, 13C) are reported.
