MERCURY(I) FLUORIDE Structural

What is MERCURY(I) FLUORIDE?

Description

Mercury(I) fluoride or mercurous fluoride, Hg2F2, consists of small yellow cubic crystals, which turn black when exposed to light. Mercury(I) fluoride is formed by the reaction of mercury(I) carbonate with hydrofluoric acid.
Hg2CO3 + 2HF→Hg2F2 +CO2 +H2O

Chemical properties

small, yellow cub crystal(s); blackens in light; preparation by reaction of Hg2CO3 and HF [MER06]

The Uses of MERCURY(I) FLUORIDE

Mercury(I) fluoride is used as antiseptic. It is used in the Swarts reaction to convert alkyl halides into alkyl fluorides.
