'''六氟砷酸五氮'''，化学式<math>\rm \ N_5^+[AsF_6]^-</math>，白色[[晶体]]，极易爆炸，爆炸时，分解出大量[[氮]]气。室温下不稳定，需在 −78°C 保存。含 <math>\rm \ N_5^+ </math> [[离子]]，该离子结构是五个氮[[原子]]呈V字型排列，由5个氮原子形成两个三键和两个单键构成。其中一个氮原子最外层只带4个[[电子]]，所以整个分子显正一价。

1999年，Christe 等利用如下反应首次制得 <math>\rm \ N_5^+[AsF_6]^-</math>：<ref>{{cite journal en|author=Karl O. Christe, William W. Wilson, Jeffrey A. Sheehy, Jerry A. Boatz|journal=[[Angew. Chem. Int.
