中文百科

氰化物

氰化物构造式

氰化物是特指带有氰离子(CN)或氰基(-CN)的化合物,其中的碳原子和氮原子通过叁键相连接。这一叁键给予氰基以相当高的稳定性,使之在通常的化学反应中都以一个整体存在。因该基团具有和卤素类似的化学性质,常被称为拟卤素。通常为人所了解的氰化物都是无机氰化物,俗称山奈或山埃(来自英语音译“Cyanide”),是指包含有氰根离子(CN)的无机盐,可认为是氢氰酸(HCN)的盐,常见的有氰化钾和氰化钠。它们多有剧毒,故而为世人熟知。另有有机氰化物,是由氰基通过单键与另外的碳原子结合而成。视结合方式的不同,有机氰化物可分类为腈(-CN)和异腈(-NC),相应的,氰基可被称为腈基(-CN)或异腈基(-NC)。

Die Struktur des Hexacyanidoferrat(II)-Anions

A cyanide is any chemical compound that contains monovalent combining group CN. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.

In inorganic cyanides, such as sodium cyanide and potassium cyanide this group is present as the negatively charged polyatomic cyanide ion (CN); these compounds, which are regarded as salts of hydrocyanic acid, are highly toxic. The cyanide ion is isoelectronic with carbon monoxide and with molecular nitrogen.
