Digermane
Digermane is an inorganic compound with the chemical formula Ge2H6. One of the few hydrides of germanium, it is a colourless gas. Its molecular geometry is similar to ethane. Digermane was first synthesized and examined in 1924 by Dennis, Corey, and Moore. Many of the properties of digermane and trigermane were determined in the following decade using electron diffraction studies. Further considerations of the compound involved examinations of various reactions such as pyrolysis and oxidation. Digermane appears to be most important as compound used to test theoretical predictions and explore similarities and differences between group 14 elements. However, there are a few applications utilizing digermane as a germanium precursor, including the formation of organic semiconductors and germanium nanowires.
== Synthesis ==
There are a variety of ways to synthesize germane. One early synthesis of digermane involved the hydrolysis of magnesium germanide using hydrochloric acid and hydrogen gas. It can be produced together with germane by the reduction of germanium dioxide with sodium borohydride, the principal product being germane. Although the major product is germane, a quantifiable amount of digermane is produced in addition to traces of trigermane. It also arises by the hydrolysis of magnesium-germanium alloys.
