6 has been identified in preparations of cobalt(III) salts and hydrochloric acid HCl in glacial acetic acid. [1] In solutions of cobalt(III) salts with chloride ions, the anionic complexes (H 2 O) 5 Co(Cl) 2+ and (H 2 O) 4 (OH)Co(Cl) + are present. [11] Trichlorides of cobalt(III) complexed with various ligands, such as organic amines, can be quite
Anhydrous cobalt(II) chloride is blue, while the hexahydrate is magenta in colour. [1] Because the color change of cobalt(II) chloride in different hydrates, it can be used to manufacture color-changing silica gel. Anhydrous cobalt halides react with nitric oxide at 70~120 °C to generate [Co(NO) 2 X] 2 (X = Cl, Br or I).
On the other hand, cobalt(III) chlorides can be obtained if the cobalt is bound also to other ligands of greater Lewis basicity than chloride, such as amines. For example, in the presence of ammonia, cobalt(II) chloride is readily oxidised by atmospheric oxygen to hexamminecobalt(III) chloride: 4 CoCl 2 ·6 H 2 O + 4 NH 4 Cl + 20 NH 3 + O 2 → ...
