TetrachloroferrateIII
Tetrachloroferrate(III) refers to the tetrachloroferrate anion, [FeCl4]−, a tetrahedral complex of iron in the +3 oxidation state. The four chloride ligands coordinate to iron in a single tetrahedral array, giving a negatively charged anion that forms salts with various countercations such as alkali metals or ammonium. In solution, stability is strongly dependent on chloride concentration and the solvent.
Formation and occurrence: [FeCl4]− is typically generated in strongly chloride-rich environments. In aqueous solution, ferric iron
Structure and properties: The iron center in [FeCl4]− is tetracoordinate and adopts a tetrahedral geometry. The
Chemistry and reactivity: Ligand exchange can occur, with chloride ligands replaced by other ligands under appropriate
Applications: Tetrachloroferrate(III) is encountered mainly in inorganic chemistry as a chlorometalate reference or synthetic intermediate and
Safety: Handling ferric salts and chloride solutions should follow standard lab safety practices to avoid irritation
