Nickel iodide is an inorganic compound with the formula NiI2. This paramagnetic bluish-black solid dissolves readily in water to give blue-green solutions.[1] The anhydrous material crystallizes with the CdCl2 motif, featuring octahedral coordination geometry at each Ni(II) center. It readily hydrates and the hydrated from can be prepared by dissolution of nickel oxide, hydroxide, or carbonate in hydroiodic acid.
NiI2 has found some industrial applications as a catalyst in carbonylation reactions.[2] It is also used as a reagent in organic synthesis, especially in conjunction with samarium(II) iodide.[3]
