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
Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3 ) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [ 12 ] and its molecule contains cobalt(II) hydrated ions ([Co(H 2 O) 6 ] 2+ ) and free nitrate ions.

trans-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine). It is a green diamagnetic solid that is soluble in water. It is the monochloride salt of the cationic coordination complex [CoCl 2 (en) 2] +. One chloride ion in this salt readily undergoes ion exchange but the two other ...
Cobalt(II) perchlorate hexahydrate is produced by reacting cobalt metal or cobalt(II) carbonate with perchloric acid, followed by the evaporation of the solution: [1] CoCO 3 + 2 HClO 4 → Co(ClO 4) 2 + H 2 O + CO 2. The anhydrous form cannot be produced from the hexahydrate by heating, as it instead decomposes to cobalt(II,III) oxide at 170 °C.
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.
CoCl 2 ·6H 2 O – cobalt(II) chloride hexahydrate SnCl 2 ·2H 2 O – tin(II) ( or stannous) chloride dihydrate For many salts, the exact bonding of the water is unimportant because the water molecules are made labile upon dissolution.
