Triethylindium is an organometallic compound. Its chemical formula is C
6H
15In.[1][2]

Synthesis

This compound can be obtained by reacting indium(III) bromide with a diethyl ether solution of Ethylmagnesium bromide:

InBr
3 + 3 C
2H
5MgBr → In(C2H5)3 + 3 MgBr
2

Other routes are also known.[3]

Properties

Indium triethyl is a colorless, toxic, oxidation and hydrolysis-sensitive liquid. It is a monomer in the gaseous and dissolved state. The compound reacts with halomethanes to form diethyl indium halides.[4]

Triethylindium is highly reactive with water:

In(C2H5)3 + H
2O → In(C2H5)2OH + C
2H
6↑

Applications

Indium triethyl is used to prepare indium phosphide layers for microelectronics.[5]
