  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...

    The body of the tables contain the characters in the respective irreducible representations for each respective symmetry operation, or set of symmetry operations. The symbol i used in the body of the table denotes the imaginary unit: i 2 = −1. Used in a column heading, it denotes the operation of inversion.

  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.

    en.wikipedia.org/wiki/Molecular_symmetry

    The symmetry group C 3v for NH 3 has the three symmetry species A 1, A 2 and E. The modes of vibration include the vibrational, rotational and translational modes. Total modes = 3A 1 + A 2 + 4E. This is a total of 12 modes because each E corresponds to 2 degenerate modes (at the same energy). Rotational modes = A 2 + E (3 modes) Translational ...

  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. 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.
