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 ...
Double fluorides include the above-mentioned fluoroanion salts, and those fluoronickelates such as NiF 4 and NiF 6.Other odd ones include an apple green coloured KNiF 3 ·H 2 O and NaNiF 3 ·H 2 O, aluminium nickel pentafluoride AlNiF 5 ·7H 2 O, ceric nickelous decafluoride Ce 2 NiF 10 ·7H 2 O, niobium nickel fluoride Ni 3 H 4 Nb 2 F 20 ·19H 2 O, vanadium nickel pentafluoride VNiF 5 ·7H 2 ...
Nickel tert-butoxide Ni[OC(CH 3) 3] 2 is coloured violet. It is formed in the reaction of di-tert-butylperoxide with nickel carbonyl. [60] Nickel dimethoxide is coloured green. [66] There are also nickel chloride methoxides with formulae: NiClOMe, Ni 3 Cl 2 (OMe) 4 and Ni 3 Cl(OMe) 5 in which Nickel and oxygen appear to form a cubane-type ...

The effective moment rises to 4.1 μ B at 4.3 K, due to ferromagnetic exchange interactions involving all three nickel ions. [4] When bound to bulkier analogues of acetylacetonate ligand, steric hindrance favors formation of the mononickel derivatives. This behavior is observed for the derivative of 3-methylacetylacetonate. [5]
