Organic germanium hydrides such as isobutylgermane ((CH 3) 2 CHCH 2 GeH 3) were found to be less hazardous and may be used as a liquid substitute for toxic germane gas in semiconductor applications. Many germanium reactive intermediates are known: germyl free radicals, germylenes (similar to carbenes), and germynes (similar to carbynes).
The first organogermanium compound, tetraethylgermane, synthesized by Winkler in 1887, [3] by the reaction of germanium tetrachloride with diethylzinc. More commonly, these Ge(IV) compounds are prepared by alkylation of germanium halides by organolithium and Grignard reagents, including surfaces terminated with Ge-Cl bonds. [4]
Two oxides of germanium are known: germanium dioxide (GeO 2, germania) and germanium monoxide, (GeO). [4] The dioxide, GeO 2 can be obtained by roasting germanium disulfide (GeS 2) or by allowing elemental germanium to slowly oxidze in air, [5] and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates. [4]
Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride.

Propagermanium , also known by a variety of other names including bis(2-carboxyethylgermanium) sesquioxide and 2-carboxyethylgermasesquioxane, is an organometallic compound of germanium [2] that is sold as an alternative medicine. It is a polymeric compound with the formula ((HOOCCH 2 CH 2 Ge) 2 O 3) n.
