Triethylindium Explained

Triethylindium is an organometallic compound. Its chemical formula is .^{[1] [2]}

Synthesis

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

+ 3 → In(C₂H₅)₃ + 3

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 + → In(C₂H₅)₂OH + ↑

Applications

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