Chlorometallate
A chloroanion is an anion that contains an element and chlorine atoms. They are also known as complex chlorides. They can occur in salts, or in solution, but not as pure acids. They mostly can be considered as chlorometallates which are a subclass of halometallates. The maximum number of chlorido- ligands around a central atom may not be as many as for fluoroanions, as the chlorine atom is bigger than the fluorine. Some chloroanions are dimeric, where there is a bond between a pair of metal atoms, or some of the chloro ligands are in a bridge position, connected to two atoms. Some chloroanions are stable in a solution in water, whereas others are decomposed. They may be stable in a molten salt, such as an ionic liquid. In the solid form some are only stable with large cations, as when there are small cations they may form two separate chloride salt phases. Chloroanions include many transition metal chloride complexes, but there are also chloroanions for main-group elements, includ ...

Transition Metal Chloride Complex
In chemistry, a transition metal chloride complex is a coordination complex that consists of a transition metal coordinated to one or more chloride ligand. The class of complexes is extensive. Bonding Halides are X-type ligands in coordination chemistry. They are both σ- and π-donors. Chloride is commonly found as both a terminal ligand and a bridging ligand. The halide ligands are weak field ligands. Due to a smaller crystal field splitting energy, the homoleptic halide complexes of the first transition series are all high spin. Only [CrCl6]3− is exchange inert. Homoleptic metal halide complexes are known with several stoichiometries, but the main ones are the hexahalometallates and the tetrahalometallates. The hexahalides adopt octahedral coordination geometry, whereas the tetrahalides are usually tetrahedral. Square planar tetrahalides are known for Pd(II), Pt(II), and Au(III). Examples with 2- and 3-coordination are common for Au(I), Cu(I), and Ag(I). Due to the presence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluoroanion
In chemistry, a fluoroanion or fluorometallate anion is a polyatomic anion that contains one or more fluorine atoms. The ions and salts form from them are also known as complex fluorides. They can occur in salts, or in solution, but seldom as pure acids. Fluoroanions often contain elements in higher oxidation states. They mostly can be considered as fluorometallates, which are a subclass of halometallates. The following is a list of fluoroanions in atomic number order. * trifluoroberyllate * tetrafluoroberyllate *tetrafluoroborate * magnesium tetrafluoride * tetrafluoroaluminate * hexafluoroaluminate *hexafluorosilicate *hexafluorophosphate * Sulfur trifluoride anion * pentafluorosulfate aka pentafluorosulfite or Sulfur pentafluoride ion * sulfur pentafluoride anion * tetrafluorochlorate * hexafluorotitanate * hexafluorovanadate(III) * hexafluorovanadate(IV) * hexafluorovanadate(V) * trifluoromanganate * hexafluoromanganate(III) * hexafluoromanganate(IV) * heptafluoromanganate ...

Tetrachloroferrate(III)
Tetrachloroferrate is the polyatomic ion having chemical formula . The metallate can be formed when ferric chloride () abstracts a chloride ion from various other chloride salts. The resulting tetrachloroferrate salts are typically soluble in non-polar solvents. The tetrachloroferrate anion, with iron(III) in the center, has tetrahedral geometry. It is useful as a non-coordinating anion comparable to perchlorate. Several organoammonium salts have been studied for their novel material properties. 1-Butyl-3-methylimidazolium tetrachloroferrate is one of several ionic liquids that are magnetic. Trimethylchloromethylammonium tetrachloroferrate is a plastic crystal that can behave as a molecular switch A molecular switch is a molecule that can be reversibly shifted between two or more stable states. The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric curren ... in response to several different typ ...

Tetrachloroaurate
Chloroauric acid is an inorganic compound with the chemical formula . It forms hydrates . Both the trihydrate and tetrahydrate are known. Both are orange-yellow solids consisting of the planar anion. Often chloroauric acid is handled as a solution, such as those obtained by dissolution of gold in aqua regia. These solutions can be converted to other gold complexes or reduced to metallic gold or gold nanoparticles. Properties Structure The tetrahydrate crystallizes as and two water molecules. The oxidation state of gold in and anion is +3. The salts of (tetrachloroauric(III) acid) are tetrachloroaurates(III), containing anions (tetrachloroaurate(III) anions), which have square planar molecular geometry.

Octachlorodimolybdate
Potassium octachlorodimolybdate (systematically named potassium bis(tetrachloromolybdate)(''Mo''–''Mo'')(4−)) is an inorganic compound with the chemical formula . It is known as a red-coloured, microcrystalline solid. The anion is of historic interest as one of the earliest illustrations of a quadruple bonding. The salt is usually obtained as the pink-coloured dihydrate. The compound is prepared in two steps from molybdenum hexacarbonyl: : : The reaction of the acetate with HCl was first described as providing trimolybdenum compounds, but subsequent crystallographic analysis confirmed that the salt contains the anion, with D4h symmetry, in which the two Mo atoms are linked by a quadruple bond. Each Mo atom is bounded with four ligands by a single bond. Each group is an regular square pyramid, with Mo atom at the apex, and four Cl atoms at the vertices of the square base of the pyramid A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are ...
