Diethylmercury is a flammable, colorless liquid, and one of the strongest known neurotoxins. This organomercury compound is described as having a slightly sweet smell, though inhaling enough fumes to notice this would be hazardous.{{Cite web|url=http://www.chemicalbook.com/ChemicalProductProperty_EN.aspx?CBNumber=CB7165894|title=Diethyl Mercury | 627-44-1|access-date=2009-01-28|archive-date=2018-10-27|archive-url=https://web.archive.org/web/20181027021631/https://www.chemicalbook.com/ChemicalProductProperty_EN.aspx?CBNumber=CB7165894|url-status=dead}}

This chemical can cross the blood–brain barrier, causing permanent brain damage. It is, however, considerably less toxic than dimethylmercury.

The resulting (CH₃CH₂)₂Hg is a dense liquid (2.466 g/cm³) that boils at 57 °C at 16 torr. This extremely toxic compound is slightly soluble in ethanol and soluble in ether.
