Chemical formula. CN ... cyanide is a C-1 synthon; i.e., it can be used to lengthen a carbon chain by ... It can mobilize some heavy metals such as mercury if present.
Mercury(II) cyanide, also known as mercuric cyanide, is a poisonous compound of mercury and cyanide. It is an odorless, toxic white powder. It is highly soluble in polar solvents such as water , alcohol , and ammonia , slightly soluble in ether , and insoluble in benzene and other hydrophobic solvents .

2 precipitating as elemental mercury and insoluble mercury(II) compounds (e.g. mercury(II) cyanide if cyanide is used as the ligand). [58] Mercury(I) chloride, a colorless solid also known as calomel, is really the compound with the formula Hg 2 Cl 2, with the connectivity Cl-Hg-Hg-Cl.
Mercury oxycyanide is a chemical compound, an organomercury derivative. It is both explosive and highly toxic, producing symptoms of both mercury and cyanide poisoning following exposure. [ 2 ] [ 3 ]
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.
