Their proper names are gallium(III) fluoride, gallium(III) chloride, gallium(III) bromide and gallium(III) iodide. GaF 3 GaF 3 is a white solid which sublimes before it melts, with an estimated melting point above 1000 °C. [contradictory] It contains 6 co-ordinate gallium atoms with a three-dimensional network of GaF 6 octahedra sharing common ...
Like the other group 13 trihalides, gallium(III) halides are Lewis acids, reacting as halide acceptors with alkali metal halides to form salts containing GaX − 4 anions, where X is a halogen. They also react with alkyl halides to form carbocations and GaX − 4. [3]: 136–137

Gallium(III) chloride is an inorganic chemical compound with the formula GaCl 3 which forms a monohydrate, GaCl 3 ·H 2 O. Solid gallium(III) chloride is a deliquescent white solid and exists as a dimer with the formula Ga 2 Cl 6. [2] It is colourless and soluble in virtually all solvents, even alkanes, which is truly unusual for a metal halide.
Gallium(III) bromide is, at room temperature and atmospheric pressure, a white, crystalline powder which reacts favorably and exothermically with water. [1] Solid gallium tribromide is stable at room temperature and can be found primarily in its dimeric form. [2] GaBr 3 can form an intermediate halide, Ga 2 Br 7; however, this is not as common ...
The reaction proceeds via a two-electron reduction of the isocyanate (O=C=N-R) by the gallylene to produce a digallacyclohexane in which the gallium atoms are in the +3 oxidation state and the C=N double bond has been cleaved. This reaction is sensitive to the substituents on the isocyanate.
The compound trimethylgallium is of some relevance to MOCVD as a precursor to gallium arsenide via its reaction with arsine at 700 °C: Ga(CH 3) 3 + AsH 3 → GaAs + 3CH 4. Gallium trichloride is an important reagent for the introduction of gallium into organic compounds.
Radii in picometers of common halogen atoms (gray/black) and the corresponding halide anions (blue) In chemistry, a halide (rarely halogenide [1]) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or ...
