[1] Nickel sulfate has some uses in the laboratory. Columns used in polyhistidine-tagging, useful in biochemistry and molecular biology, are regenerated with nickel sulfate. Aqueous solutions of NiSO 4 ·6H 2 O and related hydrates react with ammonia to give [Ni(NH 3) 6]SO 4 and with ethylenediamine to give the complex [Ni(H 2 NCH 2 CH 2 NH 2 ...
The oxalatonickelates are a class of compounds that contain nickel complexed by oxalate groups. They form a series of double salts , and include clusters with multiple nickel atoms. Since oxalate functions as a bidentate ligand it can satisfy two coordinate positions around the nickel atom, or it can bridge two nickel atoms together.
A binary compound of nickel contains one other element. Substances that contain only nickel atoms are not actually compounds. In a noble gas matrix, nickel can form dimers, a molecule with two nickel atoms: Ni 2. [1] Ni 2 has a bonding energy of 2.07±0.01 eV. For Ni 2 + the bond energy is around 3.3 eV. Nickel dimers and other clusters can ...
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
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 following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Nickel sulfide is any inorganic compound with the formula Ni x S y. These compounds range in color from bronze (Ni 3 S 2) to black (NiS 2). The nickel sulfide with simplest stoichiometry is NiS, also known as the mineral millerite. From the economic perspective, Ni 9 S 8, the mineral pentlandite, is the chief source of mined nickel.
