Tetraethyltin or tetraethyl tin is a chemical compound with the formula C
8H
20Sn and molecular structure (CH3CH2)4Sn, that is, a tin atom attached to four ethyl groups. It is an important example of an organotin compound, often abbreviated as TET.

Tetraethyltin is a colourless flammable liquid, soluble in diethyl ether and insoluble in water, that freezes at -112°C and boils at 181°C.[1][2] It is used in the electronics industry.

Tetraethyltin can be obtained by reacting ethylmagnesium bromide with tin(IV) chloride:[1]

SnCl4 + 4 (C2H5)MgBr → (CH3CH2)4Sn + 4 MgBrCl

The same reaction can be used to obtain tetra-n-propyltin and tetra-n-butyltin.[1]

Tetraethyltin is converted in the body to the more toxic triethyltin.[3]
