Hexamminecobalt(III) chloride is a salt of a coordination complex wherein six ammonia ("ammine") ligands occupy the first coordination sphere of the ion Co 3+. In hexamminecobalt(III) chloride ([Co(NH 3 ) 6 ]Cl 3 ), the cobalt cation plus the 6 ammonia ligands comprise the first coordination sphere.
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 ...
This intermediate is then heated to induce coordination of one of the outer sphere chloride ligands: [Co(NH 3) 5 (OH 2)]Cl 3 → [Co(NH 3) 5 Cl]Cl 2 + H 2 O. The dication [Co(NH 3) 5 Cl] 2+ has idealized C 4v symmetry. [3] [4] In an aqueous solution, chloropentaamminecobalt(III) chloride reforms aquopentammine complex.
In chemistry, crystallography, and materials science, the coordination number, also called ligancy, of a central atom in a molecule or crystal is the number of atoms, molecules or ions bonded to it. The ion/molecule/atom surrounding the central ion/molecule/atom is called a ligand .
In coordination chemistry, metal ammine complexes are metal complexes containing at least one ammonia (NH 3) ligand. "Ammine" is spelled this way for historical reasons; [1] in contrast, alkyl or aryl bearing ligands are spelt with a single "m". Almost all metal ions bind ammonia as a ligand, but the most prevalent examples of ammine complexes ...
The coordination geometry of an atom is the geometrical pattern defined by the atoms around the central atom. The term is commonly applied in the field of inorganic chemistry, where diverse structures are observed. The coordination geometry depends on the number, not the type, of ligands bonded to the metal centre as well as their locations.
Hexaamminecobalt(III) chloride is the chemical compound with the formula [Co(NH 3) 6]Cl 3.It is the chloride salt of the coordination complex [Co(NH 3) 6] 3+, which is considered an archetypal "Werner complex", named after the pioneer of coordination chemistry, Alfred Werner.
Coordination isomerism is a form of structural isomerism in which the composition of the coordination complex ion varies. In a coordination isomer the total ratio of ligand to metal remains the same, but the ligands attached to a specific metal ion change.
