Molar mass:312.5023 g·mol−1

Appearance:iron-black solid (anhydrous)

bluish-green solid (hexahydrate)

Density:5.384 g/cm3

Melting point:780 °C (1,440 °F; 1,050 K) (anhydrous)

                           43 °C (hexahydrate, loses water)

Solubility in water:124.2 g/100 mL (0 °C)

                                 188.2 g/100 mL (100 °C)

Solubility:alcohols

Magnetic susceptibility (χ):+3875.0·10−6 cm3/mol




Application




NiI2 has found some industrial applications as a catalyst in carbonylation reactions. It is also has niche uses as a reagent in organic synthesis, especially in conjunction with samarium(II) iodide.




Like many nickel complexes, those derived from hydrated nickel iodide have been used in cross coupling.
