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 ...
[14 C]-labeled TMA has been made by this method. [7] Although this reaction is suitable for the common halides, tetramethylammonium salts with more complex anions may be prepared by salt metathesis reactions, e.g. tetramethylammonium borohydride has been made from tetramethylammonium hydroxide as shown: [8]
4 salts are often more soluble in organic solvents (lipophilic) than the related nitrate or halide salts. Related to BF − 4 are hexafluorophosphate, PF − 6, and hexafluoroantimonate, SbF − 6, both of which are even more stable toward hydrolysis and other chemical reactions and whose salts tend to be more lipophilic.
Salts of InCl − 4, InBr − 4 and InI − 4 are known. The salt LiInF 4 has been prepared, [17] [18] however it has an unusual layer structure with octahedrally coordinated indium center. Salts of InF 6 3−, InCl 3− 6 and InBr 3− 6 [19] have all been made.
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 ...
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]
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 ...
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 ...
