  2. Copper(II) chloride - Wikipedia

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

    2 CuCl 22 CuCl + Cl 2 The reported melting point of copper(II) chloride of 498 °C (928 °F) is a melt of a mixture of copper(I) chloride and copper(II) chloride. The true melting point of 630 °C (1,166 °F) can be extrapolated by using the melting points of the mixtures of CuCl and CuCl 2 .

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

    In Cs 2 CuCl 4, CuCl 4 2− exhibits a distorted (flattened) tetrahedral geometry, whereas in [Pt(NH 3) 4][CuCl 4], it adopts a planar configuration. Green CuBr 3 − and violet CuBr 4 2− are also known. [9] Monovalent copper forms luminescent Cu n X n clusters (where X = Br, Cl, I), exhibiting diverse optical properties. [10] [11]

    [2] KCuO 2 was discovered first in 1952 by V. K. Wahl and W. Klemm, they synthesized this compound by heating copper(II) oxide and potassium superoxide in an atmosphere of oxygen. [3] 2 KO 2 + 2 CuO → 2 KCuO 2 + O 2. It can also be synthesized by heating potassium superoxide and copper powder: [4] KO 2 + Cu → KCuO 2. KCuO 2 reacts with the ...

    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.

  7. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.

  8. Copper(I) chloride - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_chloride

    2 Cu + Cl 22 CuCl. Copper(I) chloride can also be prepared by reducing copper(II) chloride with sulfur dioxide, or with ascorbic acid that acts as a reducing sugar: [13] [14] 2 CuCl 2 + SO 2 + 2 H 2 O → 2 CuCl + H 2 SO 4 + 2 HCl 2 CuCl 2 + C 6 H 8 O 6 → 2CuCl + 2HCl + C 6 H 6 O 6. Many other reducing agents can be used. [12]

  9. Square pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Square_pyramidal_molecular...

    Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand. If the ligand atoms were connected, the resulting shape would be that of a pyramid with a square base.
