Nickel nitrate is the chemical compound Ni(NO3)2 or any hydrate thereof. The anhydrous form is not commonly encountered, thus "nickel nitrate" usually refers to nickel(II) nitrate hexahydrate. The formula for this species is written in two ways. Ni(NO3)2.6H2O and, more descriptively [Ni(H2O)6](NO3)2. The latter formula indicates that the nickel(II) center is surrounded by six water molecules in this hydrated salt. The nitrate anions are not bonded to nickel.
[Ni(H2O)6](NO3)2 is highly soluble in water, giving emerald green solutions. It is a useful precursor to other nickel(II) derivatives where the water ligands would be replaced.
