  2. Tungsten hexachloride - Wikipedia

    en.wikipedia.org/wiki/Tungsten_hexachloride

    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]

  3. List of character tables for chemically important 3D point groups

    en.wikipedia.org/wiki/List_of_character_tables...

    This lists the character tables for the more common molecular point groups used in the study of molecular symmetry. These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry. Information regarding the use of the tables, as well ...

  4. Tungsten(V) chloride - Wikipedia

    en.wikipedia.org/wiki/Tungsten(V)_chloride

    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.

  5. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    Then in 1967 researchers led by Nissim Calderon at the Goodyear Tire and Rubber Company described a novel catalyst system for the metathesis of 2-pentene based on tungsten hexachloride, ethanol, and the organoaluminum compound EtAlMe 2. The researchers proposed a name for this reaction type: olefin metathesis. [19]

  6. Hexamethyltungsten - Wikipedia

    en.wikipedia.org/wiki/Hexamethyltungsten

    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.

    It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]

  8. Tungsten(II) chloride - Wikipedia

    en.wikipedia.org/wiki/Tungsten(II)_chloride

    Tungsten(II) chloride is the inorganic compound with the formula W 6 Cl 12. It is a polymeric cluster compound. The material dissolves in concentrated hydrochloric acid, forming (H 3 O) 2 [W 6 Cl 14](H 2 O) x. Heating this salt gives yellow-brown W 6 Cl 12. [1] The structural chemistry resembles that observed for molybdenum(II) chloride.

  9. Hexachloride - Wikipedia

    en.wikipedia.org/wiki/Hexachloride

    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 ...
