The ionic chemical formula of sodium cyanide (Sodium Cyanide Ionic Formula) is $Na ^ + [C ≡ N] ^ - $, and its related properties are described in classical Chinese below (because I don't know the specific requirements, it is briefly explained from its composition, properties, etc.):

Sodium cyanide is a compound. Its ionic structure is formed by sodium ion ($Na ^ + $) and cyanide ion ($[C ≡ N] ^ - $). Sodium ion, the sodium atom loses one electron and obtains a positively charged ion. It is active and often exists in various salts.

Cyanide ion is formed by connecting two elements of carbon and nitrogen with three bonds. Between carbon and nitrogen, the covalent phase is negatively charged as a whole. Sodium cyanide can dissociate in water due to the presence of these two ions, and is in an ionic state, with the characteristics of salts. However, cyanide is extremely toxic, and if people touch it or eat it, it can cause illness, and even endanger their lives. When using it, be careful and follow the procedures strictly to prevent accidents.
