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.
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]
GDP remains bound to the inactive GTPase until a GEF binds and stimulates its release. [3] The localization of GEFs can determine where in the cell a particular GTPase will be active. For example, the Ran GEF, RCC1, is present in the nucleus while the Ran GAP is present in the cytosol, modulating nuclear import and export of proteins. [8]

Nitrosyl fluoride is typically produced by direct reaction of nitric oxide and fluorine, although halogenation with a perfluorinated metal salt is also possible.The compound is a highly reactive fluorinating agent that converts many metals to their fluorides, releasing nitric oxide in the process:

This is an unusual example of a compound where the oxidation state of silver is fractional. The compound is produced by the reaction of silver and silver(I) fluoride: [1] Ag + AgF → Ag 2 F. It forms small crystals with a bronze reflex and is a good conductor of electricity.
