Tetraethylgermanium is a kind of organic germanium compounds. Germanium shares the group 14 with silicon, tin and lead in the periodic table. Though having limited synthetic value due to the cost of organic germanium compounds, germanium is considered as a non-toxic alternative of many toxic organotin reagents. Compounds such as d tetraethylgermanium are used as precursors for germanium dioxide chemical vapor deposition in the microelectronics industry, being useful in the manufacturing of semiconductor films.
