Mercury Fluoride
Mercury fluoride can refer to: * Mercury(I) fluoride (dimercury difluoride, mercury monofluoride, mercurous fluoride), Hg2F2 * Mercury(II) fluoride (mercury difluoride, mercuric fluoride), HgF2 * Mercury(IV) fluoride Mercury(IV) fluoride, HgF4, is the first mercury compound to be reported with mercury in the +4 oxidation state. Mercury, like the other group 12 elements (cadmium and zinc), has an s2d10 electron configuration and generally only forms bonds ...

Mercury(I) Fluoride
Mercury(I) fluoride or mercurous fluoride is the chemical compound composed of mercury (element), mercury and fluorine with the chemical formula, formula Hg2F2. It consists of small yellow cubic crystals, which turn black when exposed to light. Synthesis Mercury(I) fluoride is prepared by the reaction of mercury(I) carbonate with hydrofluoric acid: :Hg2CO3 + 2 HF → Hg2F2 + CO2 + H2O Reactions When added to water, mercury(I) fluoride hydrolyzes to elemental liquid mercury, mercury(II) oxide, and hydrofluoric acid: :Hg2F2 + H2O → Hg + HgO + 2 HF It can be used in the Swarts reaction to convert alkyl halides into alkyl fluorides: :2 alkyl halide, R-X + Hg2F2 → 2 R-F + Hg2X2 :where X = chlorine, Cl, bromine, Br, iodine, I Structure In common with other Hg(I) (mercurous) compounds which contain linear X-Hg-Hg-X units, Hg2F2 contains linear FHg2F units with an Hg-Hg bond length of 251 pm (Hg-Hg in the metal is 300 pm) and an Hg-F bond length of 214 pm.Wells A.F.

Mercury(II) Fluoride
Mercury(II) fluoride has the molecular formula HgF2 as a chemical compound of one atom of mercury with 2 atoms of fluorine. 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 of mercury(II) oxide Mercury(II) oxide, also called mercuric oxide or simply mercury oxide, is the inorganic compound with the formula Hg O. It has a red or orange color. Mercury(II) oxide is a solid at room temperature and pressure. The mineral form montroydite is v ...: :2 HgO + 2 F2 → 2 HgF2 + O2 with oxygen as byproduct. Applications Mercury(II) fluoride is a selective fluorination agent.

Mercury(IV) Fluoride
Mercury(IV) fluoride, HgF4, is the first mercury compound to be reported with mercury in the +4 oxidation state. Mercury, like the other group 12 elements (cadmium and zinc), has an s2d10 electron configuration and generally only forms bonds involving its 6s orbital. This means that the highest oxidation state mercury normally attains is +2, and for this reason it is usually considered a post-transition metal instead of a transition metal. HgF4 was first reported from experiments in 2007, but its existence remains disputed; experiments conducted in 2008 could not replicate the compound. History Speculation about higher oxidation states for mercury had existed since the 1970s, and theoretical calculations in the 1990s predicted that it should be stable in the gas phase, with a square-planar geometry consistent with a formal d8 configuration. However, experimental proof remained elusive until 2007, when HgF4 was first prepared using solid neon and argon for matrix isola ...
