'''二氮化硫'''是一种[[无机化合物]]，化学式为SN<sub>2</sub>，或写作N<sub>2</sub>S，它是[[氮化硫|硫的氮化物]]之一，它和[[一氧化二氮]]是[[等电子体]]。它可在苯基噻三唑的分解仲作为短寿命的中间体生成：<ref>{{cite journal|journal=The Journal of Organic Chemistry|volume=51|issue=10|language=en|issn=0022-3263|date=1986-05|pages=1908–1910|doi=10.1021/jo00360a051|url=https://pubs.acs.org/doi/abs/10.1021/jo00360a051|title=Dinitrogen sulfide|accessdate=2021-12-25|author=Curt Wentrup, Stephan Fischer, Andre Maquestiau, Robert Flammang|archive-date=2021-12-25|archive-url=https://web.archive.org/web/20211225024515/https://pubs.acs.org/doi/abs/10.1021/jo00360a051}} {{Wayback|url=https://pubs.acs.org/doi/abs/10.1021/jo00360a051 |date=20211225024515 }}</ref>
