'''二乙基汞'''，示性式：Hg(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub>，是在常溫常壓下一种易燃的无色液體，这种[[有机汞化合物]]被描述为略带甜味，它的毒性雖比[[二甲基汞]]低得多，但吸入足够的烟气仍被发现这是有害的； <ref>{{Cite web |url=http://www.chemicalbook.com/ChemicalProductProperty_EN.aspx?CBNumber=CB7165894 |title=存档副本 |access-date=2021-05-23 |archive-date=2018-10-27 |archive-url=https://web.archive.org/web/20181027021631/https://www.chemicalbook.com/ChemicalProductProperty_EN.aspx?CBNumber=CB7165894 |dead-url=no }} {{Wayback|url=http://www.chemicalbook.com/ChemicalProductProperty_EN.aspx?CBNumber=CB7165894 |date=20181027021631 }}</ref>这种化学物质可以穿过[[血腦屏障|血脑屏障]]，造成永久性脑损伤，也是已知最强的[[神經毒素|神经毒素]]之一。

== 合成 ==
[[乙基溴化镁]]与[[氯化汞]]的反应可制得二乙基汞。 <ref>{{Cite book|last=Brauer|first=Georg|url=https://www.worldcat.org/oclc/310719490|title=Handbuch der präparativen anorganischen Chemie Bd. 2.|others=Baudler, Marianne|isbn=978-3-432-87813-3|edition=3rd|location=Stuttgart|pages=1063|oclc=310719490}}</ref>
