Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO 4 (H 2 O) 6. This highly soluble turquoise coloured salt is a common source of the Ni 2+ ion for electroplating .
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 ...
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.

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 International Chemical Identifier (InChI, pronounced / ˈ ɪ n tʃ iː / IN-chee) [3] is a textual identifier for chemical substances, designed to provide a standard way to encode molecular information and to facilitate the search for such information in databases and on the web.
The known salts include (NH 4) 2 Ni 2 (SO 4) 3, K 2 Ni 2 (SO 4) 3 and Rb 2 Ni 2 (SO 4) 3, and those of Tl and Cs are predicted to exist. Some minerals are double salts, for example Nickelzippeite Ni 2 (UO 2 ) 6 (SO 4 ) 3 (OH) 10 · 16H 2 O which is isomorphic to cobaltzippeite , magnesiozippeite and zinczippeite , part of the zippeite group.
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.
