Tetraethylgermanium

Tetraethylgermanium is a chemical compound with the formula (C2H5)4Ge. It is a colorless liquid that is used as a precursor to other germanium compounds and in the production of semiconductors.

Chemical Properties

Tetraethylgermanium is a organogermanium compound that is a colorless liquid at room temperature. It has a boiling point of 160-162 °C and a density of 0.96 g/mL at 25 °C. It is soluble in most organic solvents but is hydrolyzed by water.

Synthesis

Tetraethylgermanium can be synthesized by the reaction of germanium tetrachloride with ethanol in the presence of a base such as sodium ethoxide. The reaction proceeds via a nucleophilic substitution mechanism.

Applications

Tetraethylgermanium is used as a precursor to other germanium compounds. It is also used in the production of semiconductors, particularly in the process of chemical vapor deposition (CVD). In this process, tetraethylgermanium is heated to produce a vapor that is then deposited onto a substrate to form a thin film of germanium.

Safety

Tetraethylgermanium is a flammable liquid and should be handled with care. It can cause burns and eye damage, and may be harmful if inhaled. Appropriate safety measures should be taken when handling this compound.
