    Notes: Die Löslichkeiten von Cr, Mn, Fe, Co und Ni in Quecksilber wurden untersucht. Während Cr-, Fe- und Co-„Amalgame“ aus Suspensionen der Metalle bestehen, enthalten Mn- und Ni-Amalgame intermetallische Verbindungen. Durch Zentrifugierung der Amalgame und anschließende spektrochemische bzw. kolorimetrische Analyse des flüssigen Anteils wurden bei 30° C folgende Werte gefunden: (g Metall/100 g Hg) Cr: 〈4,10-7; Mn: 1,7 · 10-3; Fe 〈5 · 10-7; Co: 〈1 · 10-6; Ni: 〈2 · 10-6. Das unterschiedliche Verhalten des Mangans und Nickels wird erörtert.

    Description / Table of Contents: Die Konstitution der grünen und braunen Eisenkomplexcyanide, welche oft als FeIIIFeIII(CN)6, angesehen wurden, ist neu untersucht worden. Durch Absorptionsspektrophotometrie im infraroten Gebiet läßt sich die Oxydationsstufe in den [Fe(CN)6]n--Ionen feststellen. Eisen(III)-hexacyanoferrat(III) konnte bisher noch nicht in reinem Zustand hergestellt werden, da die Hexacyanoferrationen dieser Verbindung schon während der Fällung sehr leicht unter dem Einfluß von Wasser reduziert werden, wobei durch Oxydation und Hydrolyse aus CN-Liganden CO2 und NH4+ entstehen. Die Reaktion läuft sogar im trockenen Zustand als Folge des eingebauten Kristallwassers weiter.
    Notes: A reinvestigation of the constitution of green and brown complex iron cyanides, often reputed to be FeIIIFeIII(CN)6, has been undertaken. Infra-red absorption spectrophotometry by means of which the valence state of iron in the [Fe(CN)6]n--ions may be identified, was used as main diagnostic tool. It was established that iron(III)-hexacyanoferrate(III) had not hitherto been prepared in the pure state as the hexacyanoferrate ions in this compound are readily reduced, under the influence of the water present during precipitation, whereby CN-ligands are oxidised and hydrolysed to CO2 and NH4+. The reaction is furthermore maintained in dry samples by water molecules included in the lattice.
