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.

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
It is the chloride salt of the coordination complex [Co(NH 3) 6] 3+, which is considered an archetypal "Werner complex", named after the pioneer of coordination chemistry, Alfred Werner. The cation itself is a metal ammine complex with six ammonia ligands attached to the cobalt(III) ion.
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 chlorides are less reactive, being bound to the metal center. The more stable cis-dichlorobis(ethylenediamine)cobalt(III) chloride is also known.
For charged complexes, ion pairing is important. Hexamminecobalt(III) chloride is a salt of a coordination complex wherein six ammonia ("ammine") ligands occupy the first coordination sphere of the ion Co 3+. In hexamminecobalt(III) chloride ([Co(NH 3) 6]Cl 3), the cobalt
In the binuclear ion [Co 2 (OH 2) 10] 4+ each bridging water molecule donates one pair of electrons to one cobalt ion and another pair to the other cobalt ion. The Co-O (bridging) bond lengths are 213 picometers, and the Co-O (terminal) bond lengths are 10 pm shorter. [10] The complexes [Mo 2 (H 2 O) 8] 4+ and [Rh 2 (H 2 O) 10] 4+ contain metal ...
Chloropentamminecobalt chloride is the dichloride salt of the coordination complex [Co(NH 3) 5 Cl] 2+. It is a red-violet, diamagnetic, water-soluble salt. It is a red-violet, diamagnetic, water-soluble salt.
