    Description / Table of Contents: Herstellung und Eigenschaften einiger sehr stabiler Nitrosylkomplexe des Rheniums werden beschrieben: ReCl3(NO), Re(OH)3(NO), M2ReCl5(NO), wobei M = K, Cs, NH4. Sie sind den entsprechenden Rutheniumkomplexen analog. Die Oxydationsstufe der Gruppe ReNO ist +3, wobei die des Re-Atoms allein aber nicht ermittelt werden konnte. Die νNO-Valenzschwingung liegt im Bereich 1710-1920 cm-;1. Das obige Kalium- und Cäsium-salz sind bei Raumtemperatur schwach paramagnetisch.
    Notes: Preparation and properties of several highly stable nitroso complexes of rhenium viz. ReCl3(NO), Re(OH)3(NO)3 M2ReCl5(NO) where M is Cs, K and NH4 are described. These are analogous to the corresponding ruthenium complexes. The oxidation number of the ‘ReNO’ unit as a whole, is +3 but that of the rhenium atom cannot be determined. The nitric oxide stretching band lies within the range of 1710-1920 cm-1. The cesium and potassium salts are weakly paramagnetic at room temperature.

    Description / Table of Contents: Reaktion von NO mit vierwertigen RheniumverbindungenStickoxid reagiert mit ReO2 bei 70-80°C quantitativ unter Bildung von Re(NO)(OH)3, ReO4- und NH4+· [Re(NO)Cl5]2- und ReO4- werden im stöchiometrischen Verhältnis sowohl bei der Reaktion von NO mit einer Suspension von ReO2 in 6 n HCl als auch in wäßrig-äthanolischer Suspension mit einem Gemisch von NO und HCl bei 70-80°C gebildet. Beim Überleiten von NO bei 220°C über Phenanthroliniumhexa-halogenorhenat(IV) wird Nitrosylhalogenid, Halogenwasserstoff und [Re(NO)(phen)Cl3] bzw. [Re(NO)(phen)Br3] gebildet.
    Notes: Nitric oxide reacts with hydrated ReO2 in aqueous suspension at 70-80°C to produce quantitatively Re(NO)(OH)3, ReO4- and NH4+. [Re(NO)Cl5]2- and ReO4- are produced in stoichiometric quantities by the reaction of either NO with ReO2 suspension in 6 N HCl or by the action of a mixture of NO and HCl with an aqueous ethanolic or aqueous suspension of ReO2 at 70-80°C. Passage of NO over 1,10-phenanthrolinium hexahalorhenate(IV) at 220°C produces nitrosyl halide, hydrogen halide and [Re(NO) (phen)Cl3] or [Re(NO)(phen)Br3].

    Description / Table of Contents: Die thermische Zersetzung der Verbindungen (MH2)[ReCl5(NO)] wurde untersucht (M = Pyridin, 2,2′-Dipyridyl bzw. 1,10-Phenanthrolin). Ausgangsverbindungen und Zersetzungsprodukte siehe „Abstract“. Die freie Säure H[ReCl4Py(NO)] zerfällt bei 200°C in [ReCl3(NO)] und [ReCl3Py2(NO)].
    Notes: Study of the thermal decomposition of (MH)2[ReCl5(NO)] where M stands for pyridine, 2,2′ dipyridyl and 1,10 phenanthroline in carbon dioxide atmosphere is described. Pyridine compound produces pyH[ReCl4py(NO)] at 250°C and [ReCl3py2(NO)] at 400°C. Dipyridyl and phenanthroline compounds produce [ReCl3(dipy)(NO)] and [ReCl3(phen)(NO)] at 210°C and 220°C respectively. The acid H[ReCl4py(NO)] decomposes under similar condition at 200°C to produce [ReCl3(NO)] and [ReCl3py2(NO)] in equivalent quantities.
