  2. Sodium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Sodium_ferrocyanide

    Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe(CN) 6] 4−. In its hydrous form, Na 4 Fe(CN) 6 · H 2 O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda. It is a yellow crystalline solid that is soluble in water and insoluble in alcohol. The yellow color is the color of ...

    en.wikipedia.org/wiki/Ferrocyanide

    Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.

    [4] Prussian blue Fe 7 18 (also (Fe 4 [Fe(CN) 6] 3 ·xH 2 O) was probably synthesized for the first time by the paint maker Johann Jacob Diesbach in Berlin around 1706. [5] [6] The pigment is believed to have been accidentally created when Diesbach used potash tainted with blood to create some red cochineal dye.

  6. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...

    Compounds that obey the 18-electron rule are typically "exchange inert". Examples include [Co(NH 3) 6]Cl 3, Mo(CO) 6, and [Fe(CN) 6] 4−.In such cases, in general ligand exchange occurs via dissociative substitution mechanisms, wherein the rate of reaction is determined by the rate of dissociation of a ligand.
