Lesser amounts of other hydrated compounds also form: e.g. Fe(SCN) 3 and [Fe(SCN) 4] −. [19] Similarly, Co 2+ gives a blue complex with thiocyanate. [20] Both the iron and cobalt complexes can be extracted into organic solvents like diethyl ether or amyl alcohol. This allows the determination of these ions even in strongly coloured solutions.

Ferric oxide, commonly called rust, is a very complicated material that contains iron(III). Iron(III) is found in many minerals and solids, e.g., oxide Fe 2 O 3 (hematite) and iron(III) oxide-hydroxide FeO(OH) are extremely insoluble reflecting their polymeric structure. Rust is a mixture of iron(III) oxide and oxide-hydroxide that usually ...
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−.

Thiocyanate complexes are not widely used commercially. Possibly the oldest application of thiocyanate complexes was the use of thiocyanate as a test for ferric ions in aqueous solution. [14] The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red.

Iron(III) nitrate, or ferric nitrate, is the name used for a series of inorganic compounds with the formula Fe(NO 3) 3. (H 2 O) n. Most common is the nonahydrate Fe(NO 3) 3. (H 2 O) 9. The hydrates are all pale colored, water-soluble paramagnetic salts.
