Nickel(II) nitrite is an inorganic compound with the chemical formula Ni(NO 2) 2. [1] Anhydrous nickel nitrite was first discovered in 1961 by Cyril Clifford Addison, who allowed gaseous nickel tetracarbonyl to react with dinitrogen tetroxide , yielding a green smoke.
Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3] It is prepared by the reaction of nickel oxide with nitric acid: NiO + 2 HNO 3 + 5 H 2 O → Ni ...
Materials that may form explosive mixtures with water and are capable of detonation or explosive reaction in the presence of a strong initiating source. Materials may polymerize, decompose, self-react, or undergo other chemical change at normal temperature and pressure with moderate risk of explosion (e.g., ammonium nitrate). 2.
Bis(2,4-pentanedionato)nickel(II) is prepared by treating nickel nitrate with acetylacetone in the presence of base. The product is the blue-green diaquo complex Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2. [9] Ni(NO 3) 2 + 2 CH 3 COCH 2 COCH 3 + 2 H 2 O + 2 NaOH → Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2 + 2 NaNO 3
Dichloro[1,2-bis(diphenylphosphino)ethane]nickel is a coordination complex with the formula NiCl 2 (dppe); where dppe is the diphosphine 1,2-bis(diphenylphosphino)ethane. It is used as a reagent and as a catalyst. [1] The compound is a bright orange-red diamagnetic solid. The complex adopts a square planar geometry. [2] [3]

Nickel nitrate commonly crystallises with six water molecules, [1] but can also be anhydrous, or with two, four or nine waters. [11] triphenylphosphine oxide nickel nitrate [(C 6 H 6) 3 PO] 2 Ni(NO 3) 2 is non ionic, with nitrato as a ligand. It can be made from nickel perchlorate. It is yellow and melts at 266 °C. [12]
