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.
Consequently, cobalt(III) chloride would spontaneously reduce to cobalt(II) chloride and chlorine. Because the reduction potential for fluorine to fluoride is so high, +2.87 V, cobalt(III) fluoride is one of the few simple stable cobalt(III) compounds.
The compound is synthesized by the reaction of cobalt(II) chloride and ethylenediamine in hydrochloric acid in the presence of oxygen: 4 CoCl 2 + 8 en + 4 HCl + O 2 → 4 trans-[CoCl 2 (en) 2]Cl + 2 H 2 O. The initial product contains HCl, which is removed by heating.

The compound is usually prepared by mixing cobalt(II) chloride, dimethylglyoxime and pyridine in an ethanolic solution. This process afford the cobaloxime(II), which is subsequently oxidized by the oxygen in air: [3] 4 CoCl 2 •6H 2 O + 8 dmgH 2 + 8 py + O 2 → 4 ClCo(dmgH) 2 py + 4 py•HCl + 14 H 2 O
