The electrochemistry of potassium heptacyanorhenate(lI1) in aqueous solution was studied by cyclic and by rotating disk voltammetry at planar microelectrodes. The results are consistent with a single, reversible electron transfer: Re(CN): + e*Re(CN)$-with Eb = 643 mV us. NHE. A single protonation equilibrium is observed:Re(CN);-+ HC&Re(CN),H3-with pK = 1.31 determined from combined voltammetric and pH data. TheRe-CN bond appears to be kinetically inert, and none of the cyano complexes in other oxidation states of Re claimed in the literature was found in the potential range -2 V to + I V.Introduction. ~ Cyano complexes of rhenium in the oxidation states 0 to VI have been claimed since more than thirty years [l] [2], and the literature is summarized in a review by Gr@h 131. In a more recent paper by Grij'th et al. [4], the existence of many of these species has been questioned, and only two of them, uiz. Re (CN

Für die Darstellung von reinem K5[Mn(CN)6] und Na5[Mn(CN)6] wird eine im Vergleich zu den bisherigen Methoden vereinfachte Arbitsweise gegeben. Die Darstellung von bläulich grünem Kaliumhexacyanorhenat(I) mit einem mindestens 90proz. Gehalt an Re+1 wird beschrieben und auf Grund quantitativer Untersuchungen sowie verschiedener Eigenschaften der Substanz die Formel K5[Re(CN)6] · 3H2O vorgeschlagen. Das erhaltene Kaliumcyanorhenat(I) verhielt sich – wahrscheinlich infolge geringer Verunreinigungen – schwach paramagnetisch. Leitfähigkeitsmessungen lieferten die molare Leitfähigkeit bei 25° C und unendlicher Verdünnung, aud DEBYE‐SCHERRER‐Aufnahmen wurden Kristallklasse und Gitterkonstante der neuen Verbindung ermittelt.

Preparation of Na3[ReII(CN)5 · H2O] by the reduction of sodium perrhenate is described. The corresponding acid has been prepared and by neutralising it, the potassium and thallium salts have been isolated. Copper, silver, cobalt and hexamine cobalt aquopentacyanorhenates (II) have been prepared. The properties of this cyano complex of bipositive rhenium are strikingly analogous to those of the cyano complexes of bipositive iron.
