Electrochemistry of the Nitroprusside Ion in Nonaqueous Solvents.

摘要

The electrochemical reduction of the pentacyanonitrosylferrate(II) anion has been studied in nonaqueous aprotic media by polarography, cyclic voltammetry and coulometry. In contrast to results from aqueous solution, the initial one electron reduction proceeds with a rapid loss of cyanide to give the blue five-coordinate tetracyanonitrosylferrate(I) anion. The tetracyanonitrosylferrate(I( anion undergoes a further quasireversible reduction and an oxidation which is reversible at fast sweep rates.
