Under normal conditions GeI 4 is a solid, GeF 4 a gas and the others volatile liquids. For example, germanium tetrachloride, GeCl 4, is obtained as a colorless fuming liquid boiling at 83.1 °C by heating the metal with chlorine. [4] All the tetrahalides are readily hydrolyzed to hydrated germanium dioxide. [4]
Organogermanium chemistry is the science of chemical species containing one or more C–Ge bonds. Germanium shares group 14 in the periodic table with carbon, silicon , tin and lead . Historically, organogermanes are considered as nucleophiles and the reactivity of them is between that of organosilicon and organotin compounds.
Germanium compounds are also used for polymerization catalysts and have most recently found use in the production of nanowires. This element forms a large number of organogermanium compounds, such as tetraethylgermanium, useful in organometallic chemistry. Germanium is considered a technology-critical element. [11]
Gallium(II) sulfide – GaS; Gallium(III) sulfide – Ga 2 S 3; Ge. Digermane – Ge 2 H 6; Germane – GeH 4; Germanium(II) bromide – GeBr 2; Germanium(II ...
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.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
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.
Germanium dioxide, also called germanium(IV) oxide, germania, and salt of germanium, [1] is an inorganic compound with the chemical formula Ge O 2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
