    Tetraethylgermanium (IUPAC name: tetraethylgermane), abbreviated TEG, is an organogermanium compound with the formula (CH3CH2)4Ge. Tetraethylgermanium is an important chemical compound used in vapour deposition of germanium which is in a tetrahedral shape.

    Synthesis

    [edit]

    Clemens Winkler first reported the compound in 1887 from diethylzinc and germanium tetrachloride, shortly after germanium was discovered in 1887.[1]
