Thiolate mercury
WebMercury (II) acetate is the chemical compound with the formula Hg ( O 2 C C H 3) 2. Commonly abbreviated Hg (OAc) 2, this compound is employed as a reagent to generate organomercury compounds from unsaturated organic precursors. It is a white water-soluble solid, but samples appear yellowish with time owing to decomposition. Webmolar ratio of mercury to thiol sulfur20 is 1:25, a reasonable approximation for the ratio in the fine fraction of the O horizon soil based on the measured Hg concentration and the

Sulfur is a "soft" atom, it's relatively large and not very electronegative. Mercury is also soft due to its very large size. Soft acids prefer to react with soft bases, and vice versa. The oxygen of alcohols, however, is hard.
