The β-diketiminato germylene hydride reported Roesky et al. crystallizes in the P2 1 /n space group as two isostructural molecules per unit. [2] X-ray crystallographic analysis of the orange-red crystals showed that the germanium atom is tetrahedrally coordinated by the hydrogen atom, the β-diketiminato ligand, and the germanium lone pair.
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.
Germanium is a chemical element ... to become a superconductor in the presence of an extremely strong electromagnetic ... Germanium hydride and germanium tetrahydride ...
The hydride adds to an electrophilic center, typically unsaturated carbon. Hydrides such as sodium hydride and potassium hydride are used as strong bases in organic synthesis. The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from ...
They are germanium analogues of alkanes. Stannane SnH 4, a strong reducing agent slowly decomposes at room temperature to tin and hydrogen gas, and is decomposed by concentrated aqueous acids or alkalis; distannane, Sn 2 H 6 is still more unstable, and longer hydrostannums (hydrotins) are unknown. Stannane and distannane are tin analogues of ...
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.

Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.
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 ]
