All Group 1 metals form halides that are white solids at room temperature. [2] A halide ion is a halogen atom bearing a negative charge. 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 ...
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 best known of these compounds is sodium chloride, table salt. [1]
It is a mixed salt containing the InBr − 4 and InBr 3− 6 anions balanced by In + cations. It is formulated In I 5 (In III Br 4 ) 2 (In III Br 6 ) The reasons for the distorted lattice have been ascribed to an antibonding combination between doubly filled, non-directional indium 5s orbitals and neighboring bromine 4p hybrid orbitals.
Halide ligands may also be displaced by the alkali salt of an X-type ligand, such as a salen-type ligand. [10] 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.
Metal halides are compounds between metals and halogens. Some, such as sodium chloride are ionic , while others such as uranium hexafluoride have considerable covalent character to their bonding. This category serves as a complement to Category:Nonmetal halides
This same basic structure is found in many other compounds and is commonly known as the NaCl structure or rock salt crystal structure. It can be represented as a face-centered cubic (fcc) lattice with a two-atom basis or as two interpenetrating face centered cubic lattices. The first atom is located at each lattice point, and the second atom is ...
The compressibility of a salt is strongly determined by its structure, and in particular the coordination number. For example, halides with the caesium chloride structure (coordination number 8) are less compressible than those with the sodium chloride structure (coordination number 6), and less again than those with a coordination number of 4 ...
In chemistry, an ionic crystal is a crystalline form of an ionic compound. They are solids consisting of ions bound together by their electrostatic attraction into a regular lattice . Examples of such crystals are the alkali halides , including potassium fluoride (KF), potassium chloride (KCl), potassium bromide (KBr), potassium iodide (KI ...
