2. Nickel(II) nitrate - Wikipedia

   en.wikipedia.org/wiki/Nickel(II)_nitrate

   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 ...

   It can be made by oxidising nickel nitrate in a cold alkaline solution with bromine. A mixed oxidation state hydroxide Ni 3 O 2 (OH) 4 is made if oxidation happens in a hot alkaline solution. A Ni 4+ hydroxide: nickel peroxide hydrate NiO 2 · H 2 O, can be made by oxidising with alkaline peroxide. It is black, and unstable and oxidises water.

   en.wikipedia.org/wiki/Nickel_oxyacid_salts

   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]

6. Nickel double salts - Wikipedia

   en.wikipedia.org/wiki/Nickel_double_salts

   Nickel thorium nitrate has formula NiTh(NO 3) 6 · 8 H 2 O. Nickel atoms can be substituted by other ions with radius 0.69 to 0.83 Å. The nitrates are coordinated on the thorium atom and the water to the nickel. Enthalp of solution of the octahydrate is 7 kJ/mol. Enthalpy of formation is -4360 kJ/mol.

9. Nickel (II) chloride - Wikipedia

   en.wikipedia.org/wiki/Nickel(II)_chloride

   Nickel(II) chloride (or just nickel chloride) is the chemical compound NiCl 2. The anhydrous salt is yellow, but the more familiar hydrate NiCl 2 ·6H 2 O is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. The nickel chlorides are deliquescent, absorbing moisture from the air to form ...
