    Description / Table of Contents: Polarographic Behaviour of Molybdenum(VI) with Special Reference to the Reactions of Molybdenum(V)The reduction of molybdenum(VI) proceeds via molybdenum(V) to molybdenum(III) in sulfuric acid. A dimerization of the formed molybdenum(V) takes place according to a D-mechanism, if hydroxide ligands are involved. The rate of dimerization is large enough to influence the polarographic picture for cH2SO4 〈 2 mol · 1-1 considerably. No experimental reference could be obtained to the existence of molybdenum(IV) during polarography. It was shown, that the preparation of very unstable solutions containing monomeric paramagnetic molybdenum(V) complexes is possible.A summary of the chemical reactions is suggested.
    Notes: Die Reduktion von Molybdän(VI) führt in Schwefelsäure über Molybdän(V) zu Molybdän(III). Enthält das sich zunächst bildende monomere Molybdän(V) Hydroxidliganden, so erfolgt eine Dimerisierung nach dem D-Mechanismus. Diese Dimerisierung ist für cH2SO4 〈 2 mol · 1-1 so schnell, daß das polarographische Bild entscheidend durch diesen Prozeß geprägt wird. Während der Reduktion gibt es keine Hinweise für das Auftreten von Molybdän(IV). Unbeständige Lösungen monomerer paramagnetischer Molybdän(V)-Komplexe konnten erhalten werden.Ein zusammenfassendes Reaktionsschema wird vorgeschlagen.
