tristetrachloroferrate

Tristetrachloroferrate is a chemical compound with the formula [FeCl4]3-. It is an ionic compound consisting of a tribasic anion, the tetrachloroferrate(III) ion, and three cations. However, the term "tristetrachloroferrate" is not a standard or recognized chemical name. The most common and stable tetrachloroferrate anion is tetrachloroferrate(III), [FeCl4]-. This anion is formed when iron is in the +3 oxidation state. When referring to the compound formed with this anion and a generic triply charged cation, it would typically be named based on that cation. For example, if the cation were triiron, the compound might be referred to as triirontetrachloroferrate, though such a compound is not commonly documented.

The tetrachloroferrate(III) ion, [FeCl4]-, is a tetrahedral species. It is typically encountered in aqueous solutions containing iron(III) and chloride ions, where it can form as a stable complex under certain conditions. The formation of tetrachloroferrate(III) is favored in solutions with high chloride concentrations. This complex plays a role in the chemistry of iron in chloride-rich environments, including some industrial processes and geological settings. The properties of compounds containing the tetrachloroferrate(III) anion depend heavily on the nature of the counterion.
