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. Approximately 40,000 tonnes were produced in 2005. [1]
When heated it dehydrates and then ends up producing nickel oxide and nickel sulfate. [5] Nickel thiosulfate NiS 2 O 3 has the same structure as the magnesium salt. It has alternating layers of octahedral shaped nickel 2+ hexahydrate, and tetrahedral shaped S 2 O 3 2− perpendicular to the β direction. [6] When heated to 90 °C it decomposes ...

Nickel amide, Ni(NH 2) 2 is a deep red compound that contains Ni 6 clusters surrounded by 12 NH 2 groups. [35] Nickel amide also forms a series of double salts. Other homoleptic nickel amides derived by substituting the hydrogen atoms are Ni[N(C 6 H 5) 2] 2 (diphenyl) and boryl amides Ni[NBMes 2 Mes] 2 and Ni[NBMes 2 C 6 H 5] 2. [36]

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.
