Nickel(II) fluoride

<p>Nickel(II) fluoride is the <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a> with the formula NiF2. It is an ionic compound of <a href="/facts/Nickel/KwMCHYRP">nickel</a> and <a href="/facts/Fluorine/YUV0Fb8m">fluorine</a> and forms yellowish to green tetragonal crystals.  Unlike many fluorides, NiF2 is stable in air.
</p><p>Nickel(II) fluoride is also produced when nickel metal is exposed to fluorine. In fact, NiF2 comprises the <a href="/facts/Passivation_(chemistry)/tPADJj5G">passivating</a> surface that forms on nickel alloys (e.g. <a href="/facts/Monel/4U7sRJRw">monel</a>) in the presence of <a href="/facts/Hydrogen_fluoride/XfQxlqR6">hydrogen fluoride</a> or elemental <a href="/facts/Fluorine/YUV0Fb8m">fluorine</a>. For this reason, nickel and its alloys are suitable materials for storage and transport these fluorine and related fluorinating agents.  NiF2 is also used as a catalyst for the synthesis of <a href="/facts/Chlorine_pentafluoride/tVTWDB0z">chlorine pentafluoride</a>.
