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
