The common halide anions are fluoride (F −), chloride (Cl −), bromide (Br −), and iodide (I −). Such ions are present in many ionic halide salts. Halide minerals contain halides. All these halide anions are colorless. Halides also form covalent bonds, examples being colorless TiF 4, colorless TiCl 4, orange TiBr 4, and brown TiI 4.
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.
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.
This reaction is formally a transmetallation, and the abstraction of the halide is driven by the precipitation of the resultant alkali halide in an organic solvent. The alkali halides generally have very high lattice energies. For example, sodium cyclopentadienide reacts with ferrous chloride to yield ferrocene: [11] 2 NaC 5 H 5 + FeCl 2 → Fe ...
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.
Oxohalide anions such as [VOCl 4] 2− can be seen as acid-base complexes of the oxohalide (VOCl 2) with more halide ions acting as Lewis bases. Another example is VOCl 2 which forms the trigonal bipyramidal complex VOCl 2 (N(CH 3) 3) 2 with the base trimethylamine. [4] The vibrational spectra of many oxohalides have been assigned in detail ...
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.
