Tetrachloroferrate is the
polyatomic ion having
chemical formula . The
metallate can be formed when
ferric chloride () abstracts a
chloride ion from various other chloride salts. The resulting tetrachloroferrate salts are typically soluble in non-polar solvents. The tetrachloroferrate
anion, with
iron(III)
In chemistry, iron(III) refers to the chemical element, element iron in its +3 oxidation number, oxidation state. In salt (chemistry), ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe3+.

The ammonium cation is a positively-charged polyatomic ion with the chemical formula or . It is formed by the protonation of ammonia (). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary a ...
salts have been studied for their novel material properties.
1-Butyl-3-methylimidazolium tetrachloroferrate
1-Butyl-3-methylimidazolium tetrachloroferrate is a magnetic ionic liquid. It can be obtained from 1-butyl-3-methylimidazolium chloride and ferric chloride. It has quite low water solubility.
Due to the presence of the high spin FeCl4 anion, the ...
is one of several
ionic liquids that are magnetic. Trimethylchloromethylammonium tetrachloroferrate is a plastic crystal that can behave as a
molecular switch in response to several different types of inputs.
