    Description / Table of Contents: Gold Complexes of Diphosphinomethanes, III. AuII Compounds by Means of Oxidative Addition of HalogenOxidative addition of halogen to the 1:2 complexes of bis(diphenylphosphino)methane and -propane with AuCl (1a, 5) leads to products which are formulated partly as AuI/AuIII compounds (2a, b), but partly also as true AuII derivatives (6a, b). The addition of iodine to the AuI complex yields an adduct of the type 4. For the characterisation of the largely insoluble materials, infrared, Mössbauer, and ESCA spectroscopy have been employed.
    Notes: Durch oxidative Addition von Halogen an 1:2-Komplexe von Bis(diphenylphosphino)methan und -propan mit AuCl (1a, 5) entstehen Produkte, die teilweise als AuI/AuIII-Verbindungen (2a, b), teilweise aber auch als echte AuII-Derivate zu formulieren sind (6a, b). Die Anlagerung von Iod an den AuI-Komplex liefert nur ein Addukt vom Typ 4. Zur Charakterisierung der fast ausnahmslos unlöslichen Substanzen wurden die Infrarot-, Mössbauer-und ESCA-Spektroskopie herangezogen.

    Notes: Neutralization-reionization mass spectrometry of silaanthracene radical cations, which are generated from the 9,10-dihydro-9-silaanthracenes 1, 3, 8 and 11 under electron-impact conditions, indicates that silaanthracenes are stable molecues in the gas phase. Flash pyrolysis of the starting compounds mentioned above also yields the silaanthracenes 2, 4, and 10, which may be isolated in an argon matrix at 15 K and exhibit characteristic UV spectra.

    Notes: Ligand exchange reactions are carried out exclusively at the unique iron site of a subsite-differentiated cyclotriveratrylene [4Fe-4S] cluster complex. The effect of a variety of thiolate, phenolate, bidentate, and bridging ligands on the redox potential of the subsite-differentiated [4Fe-4S] cluster complex is studied and compared with the effects of such ligands on an [Fe4S4C14]2- cluster. The redox potential can be modulated within the range of -1.60 to -1.80 V (vs. Fc0/+) by varying the ligand. The introduction of an electron releasing substituent shifts the redox potential to more negative values, whereas an electron withdrawing substituent has the opposite effect. A linear relationship exists between the number of substituted sites and the reduction potential of the cluster.

    Description / Table of Contents: The systems RbCl—AlCl3, CsCl—AlCl3, LiI—AlI3, RbI—AlI3, CsI—AlI3 and NH4I—AlI3 have been subjected to a thermal examination. Besides 1:1 compounds in each case, NaAl2I7 and NaAl3I10 were also found. Contrary to calculations by KRIAGOVA the theoretical inference is that, in the alkali-aluminium halides, aluminium will have a tetrahedralsurrounding. Only in fluoride complexes also an octahedral surrounding is possible.
    Notes: Die Systeme RbCl—AlCl3, CsCl—AlCl3, LiJ—AlJ3, RbJ—AlJ3, CsJ—AlJ3 und NH4J—AlJ3 wurden thermisch untersucht. Außer allen 1:1-Verbindungen wurden noch NaAl2J7 und NaAl3J10 gefunden. Im Gegensatz zu den Berechnungen von KRIAGOVA ließ sich theoretisch folgern, daß in den Alkalialuminiumhalogeniden das Aluminium eine tetraedrische Umgebung hat; nur in den Fluoridkomplexen ist auch eine oktaedrische Umgebung möglich.

    Description / Table of Contents: The systems RbCl—AlCl3 and CsCl—AlCl3 have been subjected to a thermal examination up to about 65 Mol-% alkali chloride. The existence of the compounds RbAlCl4 and CsAlCl4 has been shown.As KENDALL and coworkers in the systems NaCl—AlCl3 and KCl—AlCl3 found a miscibility gap below about 18 mol-% alkali chloride, we did an analogous observation in the now investigated systems.
    Notes: Die Systeme RbCl—AlCl3 und CsCl—AlCl3 wurden bis etwa 65 Mol-% Alkalichlorid thermisch untersucht. Es wurden die Verbindungen RbAlCl4 (c) und CsAlCl4 (c) gefunden. Wie KENDALL und Mitarbeiter in den Systemen NaCl—AlCl3 und KCl—AlCl3 fanden, gibt es auch in den beiden untersuchten Systemen eine Mischungslücke bis etwa 18 Mol-% Alkalichlorid.

    Description / Table of Contents: Komplexe von TrialkylphosphinoxidenEs wird über neue Komplexe von Trimethyl-, Tris(hydroxymethyl)-, Triethyl-, Tripropyl-, Tri-isopropyl-, Tributyl-phosphinoxid berichtet. Aussagen über die Strukturen der Komplexe werden mit Hilfe der Schwingungs- und Ligandenfeld-Spektroskopie erzielt. Die verschiedenen Faktoren, welche die Strukturen beeinflussen, werden diskutiert.
    Notes: A number of new complexes containing trimethylphosphine oxide, tris(hydroxymethyl)phosphine oxide, triethylphosphine oxide, tripropylphosphine oxide, triisopropylphosphine oxide and tributylphosphine oxide is reported. The structures of the complexes have been deduced with the aid of physical measurement such as vibrational and ligand-field spectroscopy. The various factors that influence the structure of phosphoryl solvates and adducts are discussed.

    Description / Table of Contents: A Method for the Identification of T-Atom Vacancies in the Lattices of ZeolitesSilanol groups in the lattices of zeolites can be silylated with trimethylchlorosilane and the products can be characterized by means of 29Si (CP) MAS NMR. T-atom vacancies are indicated by the formation of silylation products with three or four siloxy-linkages under mild reaction conditions as this requires the presence of three or silanol groups in favourable geometrical arrangements.
    Notes: Am Beispiel der Zeolithe ZSM-5 und Y wird gezeigt, wie amn Gitter-Leer-stellen in Zeolithen identifizieren kann. Terminale Hydroxylgruppen, die auch Gitter-Leerstellen umgeben, werden dabei mit Trimethylchlorsilan (TCS) silyliert und die Produkte mit 29Si-(CP)-MAS-NMR untersucht. Die Anwesenheit von Gitter-Leerstellen wird angezeigt durch die Bildung von Silylierungsprodukten mit drei oder vier Siloxybindungen, die Insertion des TCS zwischen drei beziehungsweise vier terminalen Hydroxylgruppen im Zeolithgitter unter sehr milden Reaktions bedingungen entstehen.
