    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.
