Appearance hygroscopic white cubic crystals

Mercury(II) fluoride has the molecular formula HgF₂.

Synthesis

Mercury(II) fluoride is most commonly produced by the reaction of mercury(II) oxide and hydrogen fluoride:

HgO + 2 HF → HgF₂ + H₂O

Mercury(II) fluoride can also be produced through the fluorination of mercury(II) chloride:

HgCl₂ + F₂ → HgF₂ + Cl₂

or mercury(II) oxide:.

2 HgO + 2 F₂ → 2 HgF₂ + O₂

Mercury(II) fluoride is a selective fluorination agent.
