Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2.The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. . Claims of the formation of tri- and tetrahydrates have not been confirmed
Many halides of cobalt(II) are known.e cobalt(II) fluoride (CoF 2) which is a pink solid, cobalt(II) chloride (CoCl 2) which is a blue solid, cobalt(II) bromide (CoBr 2) which is a green solid, and cobalt(II) iodide (CoI 2) which is a blue-black solid. In addition to the anhydrous forms, these cobalt halides also have hydrates.
Cobalt(III) chloride or cobaltic chloride is an unstable and elusive compound of cobalt and chlorine with formula CoCl 3. In this compound, the cobalt atoms have a formal charge of +3. [1] The compound has been reported to exist in the gas phase at high temperatures, in equilibrium with cobalt(II) chloride and chlorine gas.
The chloride ion in this salt readily undergoes ion exchange. The compound is synthesized by the oxidation of a mixture of cobalt(II) chloride, lithium hydroxide, and ethylenediamine in the presence of carbon dioxide: [1] CoCl 2 + 2 en + CO 2 + 0.5 H 2 O 2 + LiOH → [CoCO 3 (en) 2]Cl + H 2 O + LiCl. The cationic complex is octahedral with C 2 ...
