Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6] The structural characterization of a discrete trigonal bipyramidal GeF 5 − anion was achieved by a "naked" fluoride reagent 1,3-bis(2,6-diisopropylphenyl)imidazolium fluoride. [7]
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]

It was first reported in 1926. [7] It can also be prepared by the fluorination of carbon dioxide , carbon monoxide or phosgene with sulfur tetrafluoride . Commercially it is manufactured by the reaction of hydrogen fluoride with dichlorodifluoromethane or chlorotrifluoromethane ; it is also produced during the electrolysis of metal fluorides MF ...

4. It was the first discovered binary compound of a noble gas. [3] It is produced by the chemical reaction of xenon with fluorine: [4] [5] Xe + 2 F 2 → XeF 4. This reaction is exothermic, releasing an energy of 251 kJ/mol. [3] Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C.
Under normal conditions germanium tetraiodide (GeI 4) is a solid, germanium tetrafluoride (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. [35]
Germanium(IV) iodide reacts with tetraalkyl tin at 250 °C to form R 2 SnI 2 and R 2 GeI 2 (R= Et, Bu, Ph). [5] It reacts with germanium and sulfur at high temperatures to produce red GeSI 2 and orange Ge 2 S 3 I 2. [6]
