氫迭氮酸早在1890年卽为卡尔特斯(Curtius)所制得。它的制得,曾被门捷列夫称为1890年最伟大的成就之一。氫迭氮酸的分子式为HN_3。它的組成特殊,目前还沒有发現与它組成相似的另一种无机酸,沒有一种元素能形成与它类似的酸根。最初,人們曾把氫迭氮酸分子中的N_3基认为是环状結构;1937—1942年間用紅外光譜和电子衍射法测定后,始确知其为开鰱結构。至于氫迭氮酸分子中的化学鍵,则至今仍是一个有爭論的问题,許多
Hydrogen azide was made in 1890 by Curtius. Its preparation, which Mendeleev called one of the greatest achievements of 1890. Hydrogen azide has the formula HN_3. Its composition is special, so far it has not found another kind of inorganic acid with similar composition, and no single element can form a similar acid radical. Initially, the hydrogen azide molecule has been considered N_3 group ring structure; 1937-1942 years after determination by infrared spectroscopy and electron diffraction, it was initially known as the open silver structure. As for the chemical bonds in hydrogen azide molecules, it is still a controversial issue to date and many
