Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula W Cl 6. This dark violet-blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. [1]
The group he worked in reacted 1,4-dilithiobutane with tungsten hexachloride in an attempt to directly produce a cyclomethylenemetallacycle producing an intermediate, which yielded products identical with those produced by the intermediate in the olefin metathesis reaction. This mechanism is pairwise:
The material is prepared by reduction of tungsten hexachloride. One method involves the use of tetrachloroethylene as the reductant [2] 2 WCl 6 + C 2 Cl 4 → W 2 Cl 10 + C 2 Cl 6. The blue green solid is volatile under vacuum and slightly soluble in nonpolar solvents. The compound is oxophilic and is highly reactive toward Lewis bases.
It is sometimes erroneously called "benzene hexachloride" (BHC). They have been used as models for analyzing the effects of different geometric positions of the large atoms with dipolar bonds on the stability of the cyclohexane conformation. [1] The isomers are poisonous, pesticidal, and persistent organic pollutants, to varying degrees.
The impacts cause neutrons to spall off the tungsten atoms, and the neutrons are channelled through guides, or beamlines, to around 20 instruments, each individually optimised for the study of different types of interactions between the neutron beam and matter. The target station and most of the instruments are set in a large hall.
A hexachloride is a compound or ion that contains six chlorine atoms or ions. It is the highest chloride that an element can form. Common hexachlorides include: Molybdenum hexachloride, MoCl 6; Tungsten hexachloride, WCl 6; Rhenium hexachloride, ReCl 6; Uranium hexachloride, UCl 6; Some hexachloroanions are also known: Hexachloroaluminate [AlCl ...
The term is often used to describe metal centers, commonly the early transition metals such as titanium, niobium, and tungsten. Oxophilicity is often stated to be related to the hardness of the element, within the HSAB theory ( hard and soft (Lewis) acids and bases ), but it has been shown that oxophilicity depends more on the electronegativity ...
W(CH 3) 6 adopts a distorted trigonal prismatic geometry with C 3v symmetry for the WC 6 framework and C 3 symmetry including the hydrogen atoms. The structure (excluding the hydrogen atoms) can be thought of as consisting of a central atom, capped on either side by two eclipsing sets of three carbon atoms, with one triangular set slightly larger but also closer to the central atom than the other.
