Nickel(II) chloride (or just nickel chloride) is the chemical compound NiCl 2. ... Molar mass: 129.5994 g/mol (anhydrous) 237.69 g/mol (hexahydrate) Appearance
Hexaamminenickel chloride is the chemical compound with the formula [Ni(NH 3) 6]Cl 2. It is the chloride salt of the metal ammine complex [Ni(NH 3 ) 6 ] 2+ . The cation features six ammonia (called ammines in coordination chemistry) ligands attached to the nickel (II) ion.
NiCl 2 (dppp) is prepared by combining equal molar portions of nickel(II) chloride hexahydrate with 1,3-bis(diphenylphosphino)propane in 2-propanol. [3] Ni(H 2 O) 6 Cl 2 + dppp → NiCl 2 (dppp) + 6 H 2 O
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 cluster. [ 68 ] Other alkoxy compounds known for nickel include nickel dipropoxide, nickel di-isopropoxide, nickel tert -amyloxide, and nickel di- tert -hexanoxide. [ 69 ]
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(II) chloride is made by dissolving nickel or its oxide in hydrochloric acid. It is usually found as the green hexahydrate, whose formula is usually written NiCl 2 ·6H 2 O. When dissolved in water, this salt forms the metal aquo complex [Ni(H 2 O) 6] 2+. Dehydration of NiCl 2 ·6H 2 O gives yellow anhydrous NiCl 2. [48] Some ...
Molar mass: 96.6902 g/mol ... Nickel(II) fluoride is the ... NiF 2 is prepared by treatment of anhydrous nickel(II) chloride with fluorine at 350 °C: [2]
The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid: . NiCO 3 + 2 CH 3 CO 2 H + 3 H 2 O → Ni(CH 3 CO 2) 2 ·4 H 2 O + CO 2. The mint-green tetrahydrate has been shown by X-ray crystallography to adopt an octahedral structure, the central nickel centre being coordinated by four water molecules and two acetate ligands. [5]
