    Description / Table of Contents: Association Behaviour of Strannatranes1-Alkylstannatranes (R = Me, Et, Bu, Phenyl) associate in unpolar solvents to relatively stable trimeric units. In aqueous solution 1-methylstannatran displays no autoassociation. 1-t-Butylstannatran, 1-o-tolylstannatran, and 1-alkylthiostannatranes are monomeric in all kinds of solvents. The association behaviour is characterized by molecular mass estimation and 1H-, 13C-, and 119Sn-NMR measurements.
    Notes: Es wird über einige neue Stannatrane und Thiostannatrane berichtet und gezeigt, daß die 1-Alkylstannatrane in unpolaren Lösungsmitteln zu relativ stabilen trimeren Einheiten assoziieren. In wäßriger Lösung zeigt 1-Methylstannatran keine Selbstassoziation. 1-t-Butylstannatran, 1-o-Tolylstannatran und 1-Alkylthiostannatrane sind in allen Lösungsmitteln monomer. Das Assoziationsverhalten wird durch Molekulargewichtsbestimmung und 1H-, 13C- und 119Sn-NMR-Messungen charakterisiert.

    Description / Table of Contents: 1,4,6-Trimethyl-5,5-dialkyldiptychdiazastannolidone - Intramolecular Pentacoordinated Stannyl Derivatives of N,N′,N″-Trimethyliminodiacetic Acid AmideThe title compounds were obtained by the reaction of dialkyltin dialkoxides with N,N′,N″-trimethyl iminodiacetic acid diamide in boiling toluene. The compounds are monomeric in benzene. Their structure was investigated by 1H, 13C and 119Sn n.m.r. measurements.
    Notes: Die Titelverbindungen werden durch die Reaktion von Dialkylzinndialkoxiden mit N,N′,N″-Trimethyliminodiessigsäurediamid in siedendem Toluen erhalten. Die Verbindungen sind monomer in Benzen. Ihre Struktur wird 1H-, 13C- und 119Sn-NMR-spektroskopisch aufgeklärt.

    Description / Table of Contents: Sulphur Dioxide as Ligand and Synthon. X. The Coordination Geometry of SO2 in Bis(phosphane)-Sulphur Dioxide-Nickel(0) Complexes. Structure of Ni(PCy3)2(SO2)The SO2 coordination geometry in Ni(PR3)2(SO2) complexes with steric parameters of the coligands Θ ≫ 141° was investigated by means of IR and 31P-NMR spectroscopy. The X-ray structure of Ni(PCy3)2(SO2) is described. The hitherto discussed n2-S.O-SO2 coordination mode for this type of complexes couldn't be confirmed.
    Notes: Zur Ermittlung der SO2-Koordinationsgeometrie in Ni(PR3)2(SO2)-Komplexen deren Coliganden Kegelöffnungswinkel von Θ ≫ 141° aufweisen, wurden die IR-und 31P-NMR-Spektroskopie herangezogen. Die Einkristallröntgenstrukturanalyse von Ni(PCy3)2(SO2) wird beschrieben. Eine für diesen Komplextyp bislang diskutierte n2-S.O-Koordination des Schwefeldioxids ließ sich nicht bestätigen.
