    Description / Table of Contents: „Ytterbiumdisulfide“: A CorrectionThe still open questions concerning preparation and crystal structure of „Ytterbiumdisulfide“ could be answered now using new experimental results. The formerly investigated single crystals were not YbIIS2 but BaS2.
    Notes: Die immer noch offenen Fragen zur Darstellung und Kristallstruktur von „Ytterbiumdisulfid“ konnten nun anhand neuerer Untersuchungsergebnisse beantwortet werden. Die seinerzeit untersuchten Einkristalle waren nicht YbIIS2 sondern BaS2.

    Description / Table of Contents: Preparation, Properties and Crystal Structure of Bis(phthalocyaninato)cerium(IV)The anodic or chemical oxidation with dibenzoylperoxide of solutions of bis(phthalocyaninato)cerate(III) in dichloromethane yields selectively sparely soluble bis(phthalocyaninato)cerium(IV), [Ce(Pc(2-))2]. Green, monoclinic needles cristallize with a = 18.783(12) Å b = 18.739(16) Å c= 15.618(10) Å ß114.30(7)°; Z = 4; space group C2/c. [Ce(Pc(2-))2] is a sandwich complex in which the cerium Atom is eightfold coordinated by the isoindole nitrogens of the two staggered convex Pc-rings. The u.v.-vis., m.i.r., f.i.r. and resonance Raman spectra are consistent with the structure.
    Notes: Schwerlösliches Bis(phthalocyaninato)cer(IV), [Ce(Pc(2-))2] wird durch anodische oder chemische Oxydation mit Dibenzoylperoxid von Bis(phthalocyaninato)cerat(III), gelöst in Dichlormethan, dargestellt. Es kristallisiert in grünen monoklinen Nadeln in der Raumgruppe C2/c mit den Gitterkonstanten a = 18,783(12) Å; b = 18,739(16) Å c = 15,618(10) Å β = 14,30(7)°; Z = 4. [Ce(Pc(2-))2] ist ein sandwichartiger complex in dem das cer-Atom von den Isoindol-Stickstoff-Atomen der beiden konvex verzerrten, auf Lücke stehenden Pc- Ringe achtfach-koordiniert ist. Die UV-VIS-, MIR-, FIR- und Resonanz-Raman-Spektren stehen im Einklang mit dieser Struktur.

    Description / Table of Contents: Synthesis and Structure of the First Ternary Lead(II) Copper(I) Oxide: PbCu2O2PbCu2O2 can be prepared by solid state reaction or by precipitation from a basic aqueous solution. Single crystals of the new compound were prepared by recrystallisation from a molten mixture (PbO—Cu2O) and investigated by X-ray diffractometer technique. PbCu2O2 crystallizes isotypically with the homologue silver compound PbAg2O2 (monoclinic with a = 8.223 Å, b = 8.289 Å, c = 6.015 Å, β = 132.62°, Z = 4, space group C2h6—C 1 2/c 1). The crystallographic data from the X-ray investigation are reported. The structure is built by endless ∞1[PbO4/4]- and ∞1[CuO2/4]-chains. Pb2+ has a one-sided asymmetric coordination with four next oxygen neighbours and Cu+ forms a stretched dumbbell with two oxygen atoms.
    Notes: PbCu2O2 kann durch Feststoffreaktion oder aus alkalischer, wässeriger Lösung erhalten werden. Einkristalle der neuen Verbindung wurden aus einer erstarrten Oxidschmelze (PbO—Cu2O) präpariert und mit Vierkreisdiffraktometertechnik röntgenographisch untersucht. PbCu2O2 ist isotyp mit der homologen Silberverbindung PbAg2O2 (monoklin mit a = 8,223 Å, b = 8,289 Å, c = 6,015 Å, β = 132,62°, Z = 4; Raumgruppe C2h6—C 1 2/c 1). Die kristallographischen Daten der Röntgenstrukturanalyse werden mitgeteilt. Die Kristallstruktur ist durch ∞1[PbO4/4]- und ∞1[CuO2/4]-Ketten charakterisiert. Pb2+ hat eine einseitige Koordination mit vier nächsten Sauerstoffnachbarn. Cu+ bildet mit zwei Sauerstoffatomen eine gestreckte Hantel.
