The yellowish dihydrate, NiCl 2 ·2H 2 O, is produced by heating the hexahydrate between 66 and 133 °C. [6] The hydrates convert to the anhydrous form upon heating in thionyl chloride or by heating under a stream of HCl gas. Simply heating the hydrates does not afford the anhydrous dichloride. NiCl 2 ·6H 2 O + 6 SOCl 2 → NiCl 2 + 6SO 2 + 12HCl
Nickel chloride NiCl 2 is yellow, crystallising in the cadmium chloride structure. It can form a hexahydrate, NiCl 2 ·6H 2 O, a tetrahydrate NiCl 2 ·4H 2 O over 29 °C and a dihydrate, NiCl 2 ·2H 2 O over 64 °C. [3] Ammine complexes like hexaamminenickel chloride also exist. Nickel bromide NiBr 2 is yellow, also crystallising in the cadmium ...
Nickel acetate has the formula (CH 3 COO) 2 Ni·4H 2 O. It has monodentate acetate and hydrogen bonding. A dihydrate also exists. Nickel acetate is used to seal anodised aluminium. [1] Nickel formate Ni(HCOO) 2.2 H 2 O decomposes when heated to yield carbon dioxide, carbon monoxide, hydrogen, water and finely divided porous nickel. [2]

Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl 2 (en) 2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni 2 Cl 2 (en) 4] 2+. This blue solid is soluble in water and some polar organic solvents.
This study found that a high percentage of people with type 2 diabetes tend to be deficient in three micronutrients: vitamins D and B12 and magnesium. These are also commonly deficient nutrients ...
As a dihydrate, nickel formate is a green, odorless, non-flammable solid that is sparingly soluble in water. [2] The compound has a monoclinic crystal structure. [3] The anhydride forms on careful heating at 130–140 °C. [6] When heated in a vacuum to 300 °C, pure nickel is formed: [5] Ni(HCO 2) 2 (H 2 O) 2 → Ni + 2 CO 2 + 2 H 2 O + H 2
