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 ...
trans,trans,trans-(1,5,9 Cyclododecatriene)nickel(0) a organonickel compound with the formula NiC 12 H 18, better known as t-Ni(cdt). It is a 16-electron coordination complex featuring trigonal planar nickel (0) bound to the three alkene groups in the cyclododecatriene ligand . [ 1 ]
By reacting nickel with chalcogens, nickel sulfide, nickel selenide, and nickel telluride are formed. There are numerous sulfides: Ni 1.5 S, Ni 17 S 18 , Ni 3 S 2 ( heazlewoodite ), Ni 3 S 4 ( polydymite ), Ni 9 S 8 ( godlevskite ), NiS ( millerite ) and two other NiS forms, NiS 2 ( vaesite ) in pyrite structure.
Nickel terephthalate can be made by a double decomposition of sodium terephthalate and nickel nitrate. Nickel terephthalate precipitates. Its solubility is 0.38 g/100g water at 25 °C. In ammonium hydroxide a violet solution forms. Boiling acetic acid converts the nickel to nickel acetate.
[10] 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]
