CuCl 2 reacts with HCl or other chloride sources to form complex ions: the red [CuCl 3] − (found in potassium trichloridocuprate(II) K[CuCl 3]) (it is a dimer in reality, [Cu 2 Cl 6] 2−, a couple of tetrahedrons that share an edge), and the green or yellow [CuCl 4] 2− (found in potassium tetrachloridocuprate(II) K 2 [CuCl 4]).
[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.
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.
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.
2 Cu + Cl 2 → 2 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]
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
Another example is O(SiH 3) 2 with an Si–O–Si angle of 144.1°, which compares to the angles in Cl 2 O (110.9°), (CH 3) 2 O (111.7°), and N(CH 3) 3 (110.9°). [24] Gillespie and Robinson rationalize the Si–O–Si bond angle based on the observed ability of a ligand's lone pair to most greatly repel other electron pairs when the ligand ...
In chemistry, dimerization is the process of joining two identical or similar molecular entities by bonds.The resulting bonds can be either strong or weak. Many symmetrical chemical species are described as dimers, even when the monomer is unknown or highly unstable.
