Hexaamminecobalt(III) chloride is the chemical compound with the formula [Co(NH₃)₆]Cl₃. It is the chloride salt of the coordination complex [Co(NH₃)₆]³⁺, which is considered an archetypal "Werner complex", named after the pioneer of coordination chemistry, Alfred Werner. The cation itself is a metal ammine complex with six ammonia ligands attached to the cobalt(III) ion.
