Application

Germanium tetrachloride may be used in the microwave preparation of Ge2Cl6, a colorless crystalline material which was included in a further study of low-valent germanium compounds.GeCl4 may be used in the plasma enhanced vapor deposition of germanium chalcogenide thin films. GeCl4 in combination with triphenylphosphine may be applied for the reduction of a number of a-bromo carboxylic acid derivatives.

The Raman spectrum of Ge(2)Cl(6) shows close analogies with that of the isoelectronic [Ga(2)Cl(6)](2)(-). A band at 262 cm(-)(1) is assigned as principally a Ge-Ge stretching mode. The compound is very moisture-sensitive and decomposes readily in vacuo to give GeCl(4)
