In Cl 2, two chloride ions are outer sphere (counter ions) and one is bound to the Co(III) center: reaction with excess silver nitrate would immediately precipitate the two chloride counter ions, but the bound chloride ion would not be precipitated.Īlso known as CPACC the molecule is investigated in relation with limiting the magnesium available for mitochondria and subsequent metabolic health benefits. Werner's model accounted for the inner sphere ligands being less reactive. This Jørgensen–Bloomstrand model was overthrown by Werner who introduced the idea that coordination complexes feature metal atoms of octahedral and tetrahedral shapes, with ammonia and other ligands attached individually to the metal. Prior to Werner, the models of amine complexes postulated chains of pentavalent nitrogen centers. It was partly on the basis of his study of cobalt coordination chemistry that Alfred Werner was awarded the Nobel Prize in Chemistry. With concentrated sulfuric acid, chloropentaamminecobalt(III) chloride forms the hydrogen sulfate complex 2+.Ĭobalt complexes have been of long-standing interest in inorganic chemistry because they are numerous, easily prepared, and colorful. In an aqueous solution, chloropentaamminecobalt(III) chloride reforms aquopentammine complex. The dication 2+ has idealized C 4v symmetry. This intermediate is then heated to induce coordination of one of the outer sphere chloride ligands:Ĭl 3 → Cl 2 + H 2O

The salt is prepared with a two-step process starting with oxidizing a solution of cobalt chloride and ammonia. The compound has been of academic and historical interest. It is a red-violet, diamagnetic, water-soluble salt. Chloropentamminecobalt chloride is the dichloride salt of the coordination complex 2+.
