Thiocyanate used to be known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide: + + + The second reaction is catalyzed by thiosulfate sulfurtransferase, a hepatic mitochondrial enzyme, and by other sulfur ...
Potassium ferrioxalate contains the iron(III) complex [Fe(C 2 O 4) 3] 3−. In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+.
Thiocyanate is a common test for the presence of iron(III) as it forms the blood-red [Fe(SCN)(H 2 O) 5] 2+. Like manganese(II), most iron(III) complexes are high-spin, the exceptions being those with ligands that are high in the spectrochemical series such as cyanide. An example of a low-spin iron(III) complex is [Fe(CN) 6] 3−.
Sulfenyl thiosulfates (RSSO 3 −) react with alkali metal cyanides to give thiocyanates with displacement of sulfite. This approach has been applied to allyl thiocyanate: [6] CH 2 =CHCH 2 Cl + Na 2 S 2 O 3 → CH 2 =CHCH 2 S 2 O 3 Na + NaCl CH 2 =CHCH 2 S 2 O 3 Na + NaCN → CH 2 =CHCH 2 SCN + Na 2 SO 3. Sulfenyl chlorides (RSCl) also convert ...

Iron(III) chloride forms a 1:2 adduct with Lewis bases such as triphenylphosphine oxide; e.g., FeCl 3 (OP(C 6 H 5) 3) 2. The related 1:2 complex FeCl 3 (OEt 2) 2, where Et = C 2 H 5), has been crystallized from ether solution. [14] Iron(III) chloride also reacts with tetraethylammonium chloride to give the yellow salt of the tetrachloroferrate ...
