    Notes: Difluorosilanethione F2Si=S (1) has been synthesized by Flash Vacuum Pyrolysis of (F3Si)2S at ≥ 500 °C and trapped in an Ar matrix. Furthermore, 1 has been obtained by co-deposition of SiS and F2/Ar and by pyrolysis of a matrix-isolated SiS2-XeF2 complex under cryogenic conditions. All six vibrational fundamentals of 1 have been observed in the matrix IR spectrum. Ab initio calculations at the MP2 and CCSD(T) levels using large basis sets have been performed. These calculations have guided the detection of 1 and the vibrational assignment. The best estimate of the structure of 1 with C2v symmetry is: r(Si=S) 191.1(1) pm, r(SiF) 156.1(1) pm, ki(FSiF) 103.3(2)°.

    Donorstabilisiertes Aluminium(I)-iodidIn memoriam Professor Wilhelm Klemm (1996)

    Description / Table of Contents: Donorstabilized Aluminium(I) IodideA metastable solution of AlI-iodide is formed by quenching of gaseous AlI-iodide, formed from Al(I) and HI(g) at about 1000°C with a mixture of toluene/diethylether. Using triethylamine as donor and solvent crystalline (AlI · NEt3)4 1 can be isolated: a planar Al4 ring with an Al—Al distance of 265 pm is the most important structural feature in this first roomtemperature stable AlI-Iodide.
    Notes: Nach Abschrecken von gasförmigem AlI-iodid, das bei Temperaturen um 1000°C aus Al(fl) und HI(g) erzeugt wird, erhält man metastabile Lösungen von AlI-iodid in einem Toluol/Diethylether-Gemisch. Mit Triethylamin als Donor und Lösungsmittel kann kristallines (AlI · NEt3)4 1 isoliert werden. Die Röntgenstrukturanalyse zeigt, daß ein planarer Al4-Ring vorliegt. Die Al—Al-Bindung in diesem ersten bei Raumtemperatur stabilen AlI-iodid entspricht mit 265 pm dem Wert einer typischen Al—Al-Einfachbindung.
