    Notes: Es ist schon sehr lange bekannt, daß sich manche Übergangsmetallsulfide in wäßrigem Ammoniumpolysulfid lösen. Obwohl anzunehmen war, daß sich dabei Metallpolysulfide bilden, hat man sich diesem Verbindungstyp erst in den letzten Jahren intensiver zugewandt. Dabei konnte eine Fülle neuer Komplexe mit Polysulfido-Chelatliganden Sn2- (n=2,3,4…) isoliert und charakterisiert werden. Die Komplexe interessieren bezüglich ihrer Struktur und Reaktivität, aber auch im Hinblick auf mögliche Anwendungen; mit ihnen können Schwefelringe definierter Größe gezielt hergestellt werden, und es deutet sich an, daß sie auch in der Katalyse Verwendung finden könnten.

    Notes: It has been long known that certain transition metal sulfides dissolve in aqueous ammonium polysulfide. Although it was assumed that they thereby formed metal polysulfides, attention was first paid to such compounds only a few years ago. In recent years a host of new complexes with polysulfido chelate ligands have been isolated and characterized. The complexes are of interest not only regarding their structure and reactivity but also in view of their potential uses; they can be used for the directed preparation of sulfur rings of a given size, and there are indications that they will find applications in catalysis.
