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.
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 ]
Nickel(II) sulfate is produced in large amounts by dissolving nickel metal or oxides in sulfuric acid, forming both a hexa- and heptahydrate [46] useful for electroplating nickel. Common salts of nickel, such as chloride, nitrate, and sulfate, dissolve in water to give green solutions of the metal aquo complex [Ni(H 2 O) 6 ] 2+ .
The geometry of the nickel(II) ion is square planar. [2] It is surrounded by two equivalents of the conjugate base (dmgH − ) of dimethylglyoxime (dmgH 2 ). The pair of organic ligands are joined through hydrogen bonds to give a macrocyclic ligand .
The blue isomer is prepared by treating hydrated nickel chloride with triphenylphosphine in alcohols or glacial acetic acid: [1] NiCl 2 •6H 2 O + 2 PPh 3 → NiCl 2 (PPh 3 ) 2 + 6 H 2 O When allowed to crystallise from chlorinated solvents, the tetrahedral isomer converts to the square planar isomer.
