==制备及结构==
氙和氮在高压下（5 GPa）化合，形成I型的Xe(N<sub>2</sub>)<sub>2</sub>，将压力升高至14 GPa，发生相变，生成II型的Xe(N<sub>2</sub>)<sub>2</sub>。<ref name=Nature>{{cite journal|title=Formation of xenon-nitrogen compounds at high pressure|journal=Scientific Reports|volume=6|pages=34896|date=2016-10-17|doi=10.1038/srep34896|issn=2045-2322|url=https://www.nature.com/articles/srep34896|language=en|accessdate=2019-01-28|author=Eugene Gregoryanz, Philip Dalladay-Simpson,  Mungo Frost, Jack Binns, Robin Turnbull, Ross T.
