Beim Ansäuern wäßriger Lösungen von WS2−4 tritt Polymerisation ein und zwar bei gleichzeitig erfolgender Reduktion des Zentralatoms. Aus der Lösung läßt sich W3OS2−8 z. B. als [(CH3)4N]+‐Salz ausfällen. Der diamagnetische Dreikernkomplex wird wie W3S2−9 durch WW‐Wechselwirkung stabilisiert.
Formation of the η‐disulfidomolybdenum(V) group by a novel intramolecular redox process has been observed on warming aqueous solutions of dithiomolybdate(VI). The structure of the anion in the orange‐red crystals of (1) was determined by X‐ray methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
