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. 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.
