Zinc cyanide is the inorganic compound with the formula Zn 2. It is a white solid that is used mainly for electroplating zinc but also has more specialized applications for the synthesis of organic compounds .
The use of zinc alkyls has been largely superseded by the use of the more easily handled Grignard reagents. This demonstrates yet another connection between the chemistries of zinc and magnesium. Zinc cyanide, Zn(CN) 2, is used as a catalyst in some organic reactions. [26] Organometallic compounds of zinc(I) contain M—M bonds.
Cyanide is quantified by potentiometric titration, a method widely used in gold mining. It can also be determined by titration with silver ion. Some analyses begin with an air-purge of an acidified boiling solution, sweeping the vapors into a basic absorber solution. The cyanide salt absorbed in the basic solution is then analyzed. [47]

Typical diorganozinc complexes have the formula R 2 Zn. Dialkylzinc compounds are monomeric with a linear coordination at the zinc atom. [7] A polar covalent bond exists between carbon and zinc, being polarized toward carbon due to the differences in electronegativity values (carbon: 2.5 & zinc: 1.65).
Modifications have shown that it is possible to use sodium cyanide or cyanogen bromide in place of hydrogen cyanide. [3] The reaction can be simplified by replacing the HCN/AlCl 3 combination with zinc cyanide. [4] Although it is also highly toxic, Zn(CN) 2 is a solid, making it safer to work with than gaseous HCN.

The cyanate ion is an anion with the chemical formula OCN −. It is a resonance of three forms: [O − −C≡N] (61%) ↔ [O=C=N − ] (30%) ↔ [O + ≡C−N 2− ] (4%). Cyanate is the derived anion of isocyanic acid , H−N=C=O, and its lesser tautomer cyanic acid (a.k.a. cyanol), H−O−C≡N.
