    Description / Table of Contents: Crystal and Molecular Structure of Tris(1,1-diethyl-3-benzoyl-thioureato)ruthenium(III)The crystal and molecular structure of tris(1,1-diethyl-3-benzoyl-thioureato)-ruthenium(III) has been determined by an X-ray structure analysis. The compound crystallizes in the trigonal space group P3 with a = 16.556, c = 8.476 Å and Z = 2. The structure was solved by Patterson methods and refined to a final R value R = 0.074 for 801 observed reflections. The molecule has the symmetry C3. The coordination polyhedron is an octahedron with facial arrangement of the ligator atoms. The Ru—S and Ru—O distances are 2.293 Å and 2.047 Å, respectively.

    Notes: A structural determination of the high-temperature form γ-Sn2F6 has been performed using neutron diffraction. This mixed fluoride exhibits the cubic ordered ReO3-type structure (Fm3m space group) with a = 8.321(4) Å at 497 K. The bond lengths SnII—F and SnIV—F give evidence of the presence of tin(II) in the (a) site and tin(IV) in the (b) site. A cationic ordering has also been found in the intermediate form β-Sn2F6 whose structure is related to the LiSbF6-type.

    Description / Table of Contents: Preparation and Crystal Structure of Cs2HgPdCl6, a Distorted Variant of ChloroperovskitsCs2HgPdCl6 single crystals show tetragonal symmetry with the space group I 4/m m m (No. 139) with 2 formular units per unit cell. The lattice parameters are a = 7.432(4) Å, c = 10.874(7) Å. The atomic arrangement of Cs2HgPdCl6 is explored by X-ray crystal structure analysis. The important polyhedrons are square-planar PdCl4 groups and HgCl2 dumbbells. The PdCl4 group is completed by two further chlorine atoms to a elongated octahedron and four further chlorine atoms form with the HgCl2 dumbbell a compressed octahedron. The crystal structure of Cs2HgPdCl6 is compared with the arrangement in halogenoperovskits and in Rb2PdCl4 [3].
    Notes: Die Verbindung Cs2HgIIPdIICl6 läßt sich durch Festkörperreaktion phasenrein darstellen. Sie kristallisiert in der Raumgruppe I 4/m m m (No. 139) mit a = 7,432(4) Å, c = 10,874(7) Å, Z = 2. Die Kristallstruktur wurde mit röntgenographischen Methoden an Einkristallen ermittelt. Pd2+ ist quadratisch-planar und Hg2+ hantelförmig von Cl-umgeben. In zweiter Nachbarschaft ergänzen weitere Cl- zu gestreckten bzw. gestauchten Oktaedern. Dieses Bauprinzip entspricht dem Aufbau von Cs2AuIAuIIICl6 [1, 2]. Es besteht direkte kristallchemische Beziehung zur Kristallstruktur der Halogenoperowskite bzw. des K2PdCl4-Typs.

    Description / Table of Contents: CO-Hydrierung an Kalium-promotierten, aus Cyanid-Komplexen hergestellten Eisen-, Cobalt- und NickelkatalysatorenKalium-promotierte Katalysatoren wurden durch Adsorption von K4[Fe(CN)6], K3[Co(CN)6] bzw. K2[Ni(CN)4] an γ-Al2O3 mit nachfolgender H2-Behandlung sowie mit und ohne vorhergehender Calcinierungsstufe dargestellt, um den Einfluß der Vorbehandlung auf die katalytischen Eigenschaften zu untersuchen. Einige Charakteristika der Katalysatoren wurden nach der Reaktion mit Hilfe der Mößbauer- und Röntgenphotoelektronenspektroskopie untersucht. Die katalytischen Eigenschaften bei der CO-Hydrierung wurden durch die Vorbehandlungsbedingungen beeinflußt, insbesondere bei den Eisenkatalysatoren. Eine hohe Selektivität für Olefine und ein niedriger Anteil an langkettigen Kohlenwasserstoffen ergab sich in der Reaktion an nichtcalcinierten Eisenkatalysatoren. Für Eisenkatalysatoren wurden ferner bemerkenswerte Unterschiede in der Anderson-Schulz-Flory-Verteilung der KW in Abhängigkeit von der Katalysator-Vorbehandlung gefunden. Entsprechende Unterschiede bei den Cobalt-haltigen Katalysatoren waren jedoch geringer. Die CO-Hydrierung an Kalium-promotierten Nickelkatalysatoren ergab einen hohen Anteil an langkettigen KW und eine hohe Selektivität für Olefine im Vergleich zu unpromotierten Nickelkatalysatoren.
    Notes: Several potassium promoted catalysts have been prepared by adsorption of K4[Fe(CN)6], K3[Co(CN)6] and K2[Ni(CN)4] on acid-modified γ-alumina. Subsequent H2 treatment with or without previous calcination step has been carried out in order to study the influence of the sample pretreatment on the catalytic behavior in the CO hydrogenation reaction. Some characteristics of the catalysts have been studied after reaction by means of Mössbauer and X-ray photoelectron spectroscopic techniques. The catalytic properties for CO hydrogenation were found to be affected by the pretreatment conditions, especially for iron catalysts. A high selectivity to olefins and a low production of long chain hydrocarbons were obtained in the reaction over non-calcined iron catalysts. For iron catalysts noticeable differences in the Anderson-Schulz-Flory distribution of hydrocarbons were induced by the catalyst pretreatment. Such differences induced by catalyst pretreatments were, however, smaller for cobalt-containing catalysts. In the CO hydrogenation on potassium-promoted nickel catalysts a high production of long chain hydrocarbons and a high selectivity to olefins were found when compared to the unpromoted nickel-catalysts.
