Nickel(II) fluoride is the chemical compound with the formula NiF2. Yellowish to green tetragonal crystals.Unlike many fluorides, NiF2 is stable in air. NiF2 comprises the passivating surface that forms on nickel alloys, e.g. monel, which is why such materials are good to store or transport hydrogen fluoride or elemental fluorine. Nickel is one of the few materials that can be used to store fluorine because it forms this coating. It is also used as a catalyst for the synthesis of chlorine pentafluoride.
NiF2 is prepared by treatment of anhydrous nickel(II) chloride with fluorine at 350 °C
