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 theoretically tennesside compound.
The halogens may either be bonded to another element through covalent bonding or (as in many metal halides) present in the form of the halide ion. Subcategories This category has the following 13 subcategories, out of 13 total.
Two commercially important halide minerals are halite and fluorite. The former is a major source of sodium chloride, in parallel with sodium chloride extracted from sea water or brine wells. Fluorite is a major source of hydrogen fluoride , complementing the supply obtained as a byproduct of the production of fertilizer.
Halide ligands may be abstracted by silver(I), often as the tetrafluoroborate or the hexafluorophosphate. In many transition metal compounds, the empty coordination site is stabilized by a coordinating solvent like tetrahydrofuran. Halide ligands may also be displaced by the alkali salt of an X-type ligand, such as a salen-type ligand. [10]
With halide ions there are examples of all of these geometries along with some anions with octahedrally coordinated indium and with bridging halogen atoms, In 2 X 3− 9 with three bridging halogen atoms and In 2 X − 7 with just one. Additionally there are examples of indium with square planar geometry in the InX 5 2− ion.
Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen.These compounds are the often commercially significant sources of these metals and halides.
The complexation depends on halide ion numbers, atomic number of the alkali metal, the halide of which is added, temperature and solution ionic strength. [9] The tetrachloride is obtained upon dissolving the dioxide in hydrochloric acid; to prevent the exothermic decomposition, it is kept under concentrated sulfuric acid.
The Halide Class includes minerals with a halogen as the major anion: fluorine F ...
